0:00Hello mga kabuhay ang tatalakayin natin
0:03ay tungkol sa active transport ano-ano
0:05ba ang iba't ibang uri ng active
0:07transport na nagaganap sa loob ng ating
0:09cell mga kabuhay may dalawang
0:11classification ang transport across the
0:14cell membrane So merong passive and
0:16active transport Meron po akong bukod na
0:19video about passive transport at kung
0:22ano-ano ang uri nito pero tingnan po
0:24natin Ong larawan sa passive transport
0:27without exerting energy madali niya p na
0:30Ibaba yung bilog dito sa bundok pero
0:32tingnan po natin yung active transport
0:34or sabi po niya This is tough so
0:37kailangan po niya ng energy para
0:42ma-malawak hawak niya against the force
0:45of Gravity so meaning mga kabuhay Meron
0:48pong mga substances sa loob ng ating
0:52katawan na kailangan pong
0:56mai-post a cell membrane kaya ito po ang
1:00meaning ng active transport molecules
1:02move from an area of low concentration
1:05to an area of High concentration kaya
1:08Makikita natin dito sa larawan Meron
1:10pong mga molecules dito sa labas ng
1:12ating cell at sa loob ng ating cell at
1:15may mga channel o tinatawag po nating
1:17mga protein pump na nakalagay po sa mga
1:21plasma membrane or cell membrane na
1:23nagiging daanan ng mga molecules Saan po
1:26ang flow from low concentration
1:30sa kakaunti po Papunta po sa mataas yung
1:34concentration or sa Marami na mga
1:36molecules kaya mga kabuhay sa active
1:39transport it requires energy in the
1:42process na tinatawag po nating ATP or
1:46adenosine triphosphate Ito po yung
1:48currency ng energy sa loob po ng ating
1:52katawan mga kabuhay isaisahin na po
1:54natin Ano yung dalawang types ng active
1:57transport number one Ito po yung Typical
2:00example ng active transport is the
2:02sodium potassium pump transport Meron
2:05pong mga protein na tinatawag na pump na
2:08naka embedded po sa plasma membrane or
2:11cell membrane especially po itong sodium
2:14potassium pump transport ay napakahalaga
2:17po sa katawan natin lalo na sa mga nerve
2:19cells so nagbibigay po ito ng
2:22electrolytes sa atin pong muscle at sa
2:25mga nerve cells po natin paliwanag po
2:28dito in this mechanism C three sodium
2:31are pumped out of the cell for every two
2:34potassium ions pump in mga kabuhay Gaano
2:37ba kahalaga ang sodium and potassium sa
2:40ating nerve cells so They are both
2:42essential dietary minerals na nakukuha
2:45po natin sa mga kinakain po natin or
2:48vitamins and they are also called
2:50electrolytes meaning Sila po yung mga
2:53ions na charge particles conduct ng
2:56electricity sa ating mga nerve cells So
2:59ibig sabihin kapag naging imbalance po
3:02ang sodium and potassium sa ating
3:04katawan so Pwede pong mag-increase yung
3:07risk na pwede kang ma-high blood
3:09magkaroon ka ng sakit sa puso Diabetes
3:12at iba pa so ang sodium Ito po ay
3:15principal ion in the fluid outside of
3:19the cell so meaning po ang sodium ay
3:22mahalaga sa labas ng ating cell kasi
3:25meron po tayong tinatawag na
3:27extracellular fluid ang sodium 10 times
3:31ang higher concentration outside of
3:33cells than inside of the cell so Itong
3:36mga carrier proteins na tinatawag po
3:39nating mga pumps with specific ions or
3:42molecules they can change shape para po
3:46makalabas Itong mga ions na to Katulad
3:48po ng sodium ang shape po niya ay bilog
3:51dito po dadaan yung sodium palabas po ng
3:55cell So ilang sodium PR sodium ions ay
3:59mas mataas po ang concentration sa labas
4:01ng cell Sabi nga ho 10 times so meaning
4:04po it moves against the concentration
4:07gradient Paano po siya nagmo-move mga
4:09kabuhay kailangan po ng ATP or energy so
4:14tingnan naman po natin ang potassium ang
4:16potassium po is a principal ion in the
4:19fluid inside the cell so sa loob naman
4:23ng cell mataas ang concentration 30
4:27times higher inside of cells than
4:30outside of the cells meaning potassium
4:33move into the cell against the
4:36concentration gradient so kailangan din
4:39po niya ng energy ilang potassium po ang
4:42kailangan makapasok po sa loob ng ating
4:45cell two potassium ions kaya tandaan
4:49natin mga kabuhay na sa bawat tatlong
4:52sodium molecules na lumalabas po sa
4:54ating cell Meron pong dalawang potassium
4:57ions ang pumapasok sa ng ating cell
5:01against the concentration gradient at sa
5:03tulong po ng ATP or energy the second
5:07type of active transport ay tinatawag
5:10pong vesicle transport or bulk transport
5:13Meron pong mga movement yung mga
5:15macromolecules yung mga malalaking
5:17molecules inside and outside sa ating
5:20cell na kailangan din po ng energy like
5:23protein polysaccharide or sugars na
5:26tinatawag kong bulk transport mga
5:29kabuhay Meron po itong dalawang uri Ito
5:31po ang endocytosis and
5:34exocytosis so una nating talakayin what
5:37is endocytosis meaning large substances
5:41can be taken in by the cell through a
5:44process called endocytosis so meron po
5:47itong tatlong uri ito ang pag cytosis
5:51pinocytosis and receptor mediated
5:54endocytosis so mga kabuhay isa-isahin po
5:57natin Una yung apag cytosis tinatawag
6:01din po itong cell eating so the cell
6:04which is called apag cyte engulfs large
6:08solids objects which may be in the form
6:10of large molecules Or Another type of
6:14organisms so Magbigay po tayo ng example
6:16ng pag cytosis Katulad po nito white
6:19blood cell or mga soldiers ng body natin
6:23So anong ginagawa po niya sa mga
6:25bacteria in- engulf niya nagkakaroon po
6:28ng vesicle pinches off from the membrane
6:32tapos yung pseudopods no yung false na
6:36arm niya para ma engulf niya Iyung
6:39bacteria in the form of food vacu na
6:42tinatawag nating phagosome solid
6:44particles Ang ineng ng pag cytosis use
6:49po itong food vacu or the pagos doon sa
6:52lysosome no na meron po ang mga white
6:56blood cell tandaan po natin ang lysosome
6:59meron po itong hydrolytic enzymes na
7:02pwedeng magd Digest dun sa in engulf na
7:05solid particles ng ating cell which is
7:08the bacteria then kapag po
7:10na-destino na po ng tinatawag na
7:14exocytosis kaya mga kabuhay ito po ang
7:17mga immune cell natin yan so i- engulf
7:20niya itong bacteria mga soldiers ng
7:22ating body which is the monocyte ang
7:25pangalawang uri po ng endocytosis ay
7:27tinatawag na pinocytosis
7:29or cell drinking so the cell takes in
7:32small drops of extracellular fluid from
7:35the environment So makikita natin mga
7:38kabuhay yung mga fluid na nasa labas ng
7:41ating cell which is the extracellular
7:43fluid makita din po natin na nagfo-focus
7:59ay yung egg cells are nourished by their
8:02surroundings through pinocytosis
8:05tandaan natin mga kabuhay sa pinocytosis
8:07there is non-specific process no in
8:11which the cell takes in Whatever solutes
8:15that are dissolved in the liquid it
8:17envelop so kahit po third type po ng
8:20endocytosis ay tinatawag na receptor
8:23mediated endocytosis
8:26extremely selective process of of
8:29importing materials into the cell nakita
8:32po natin na may mga receptors protein
8:35dito po sa Pit makikita natin sa cell
8:38membrane ang tawag po natin dito ay mga
8:41Katrin Ito po yyung mga depress areas of
8:45the cell membrane called coated Pit Okay
8:50so the Pit covers the molecules when the
8:53receptors are triggered then pag
8:55nakapasok na po sa loob ng ating cell
8:58pareho din po po ng pinocytosis and
9:01phagocytosis Okay nagiging coated
9:04vesicle po siya sa loob ang ldl Okay is
9:08a bad cholesterol is taken Up by the
9:11cell through receptor mediated
9:13endocytosis dahil meron tayong High
9:16density lipoprotein which is a good
9:19cholesterol so Ito po Iyung actual na
9:22view or picture na nangyayari po sa cell
9:26mediated receptor endocytosis
9:29kakain natin ang pangalawang uri ng bulk
9:31transport or vesicle transport na
9:34nangyayari po sa ating cell ito ang
9:36exocytosis So Anong meaning the release
9:39of substances from the cell is called
9:42exocytosis so meaning ang mga materials
9:44are exported out of the cell via
9:48secretory vesicles mga kboy explain
9:50natin kung ano nangyayari sa
9:52exocytosis so Sabi po dito sa
9:54explanation The products to be excreted
9:57from the cell are first in case in a
9:59vesicle kaya Makikita po natin na itong
10:02transport vesicle and also the secretory
10:04vesicle nakaen close po yung mga
10:07ire-release outside of the cell which
10:10then move toward the cell membrane so
10:12Dito po sila mag-u sa pinaka plasma
10:15membrane natin or cell membrane it will
10:18release its content out of the cell and
10:21into the environment then the vesicle
10:23finally become part of the cell membrane
10:26mga kabuhay tandaan natin yung fuse
10:28meaning nagsama no yung mga vesicle at
10:32the same time yung ating plasma membrane
10:34at Dito din po i-restore yung normal
10:37amount ng plasma membrane and any
10:40molecules na naka-ol po in the fluid
10:43contents of this vesicle So meaning
10:47nare-relax
10:53At tandaan din po natin na meron tayong
10:56tatlong uri or tatlong common pathways
10:59of exocytosis na nangyayari po sa loob
11:03ng ating cell first is the constitutive
11:06exocytosis na p-pero po ito ng lahat ng
11:11ating body cells na ito yung proseso na
11:14dini-deliver nila iyung mga membrane
11:17protein and lipids to the cell surface
11:20Ito po sa cell membrane and also helps
11:24in the elimination of the substances
11:26from the cells exterior kapag naman po
11:29regulated secretion or tinatawag po
11:32nating
11:36non-consensual signals so meaning po
11:44ini-insist so most common po ito sa mga
11:48secretory cells like neurons Hindi po
11:51ito nangyayari sa ibang cells po na nasa
11:54loob ng katawan natin at ang pangatlong
11:57pathway po sa exocytosis ay tinatawag na
12:01vesicular
12:02exocytosis So makikita po ito sa mga
12:05bacteria Katulad po ng process na pag
12:07cytosis wherein Iyung bacteria Once na
12:11naeng na ng ating white blood cell magp
12:15fuse po ito sa lysosome kaya tinatawag
12:17na pago lysosome then magre-release yung
12:21lysosome ng digestive and hydrolytic
12:24enzyme to help to break down yung
12:27materials na nasa loob ng vesicle na yun
12:30na nga po yung bacteria so once po na
12:33na- Breakdown na yan then it will
12:35release outside the cell Katulad po nito
12:38which is the post digestion m kabuhay
12:41magbigay pa tayo ng mga example Iyung
12:43hormones are released by the endocrine
12:45glands also using the
12:48exocytosis pati iung mga waste product
12:50natin mga kabuhay hanggang dito lamang
12:52po ang ating naging talakayan tungkol sa
12:55active transport at nalaman po natin na
12:57meron onong iba't ibang uri at nagbigay
13:00tayo ng mga example sana magamit niyo
13:02ito sa inyong pag-aaral Good luck mga
13:04kabuhay at huwag po kayong magsawa na
13:07makinig sa aking mga educational video
13:10at kung meron po kayong mga isa-suggest
13:12na mga topic Pwede niyo po akong
13:14i-message Lagi nating tatandaan ingatan
13:17natin ang ating kalusugan God bless
13:19everyone bye
