    II.            Study Matter

Transport by Cell Membrane

Cell membrane or plasma membrane locate beside sitoplasma out dissaggregate living cell with not living area beside it. In the sitoplasma contyain organels, those all organel also  wrapped by membrane structure it samely with cell membrane it is lipid, protein, and less carbohidrat. Cell membrane funct as b oundary between cell organels in the deep part and liquid be bathed cell. Transport by cell membrane divided 2 part is passive transport and active membrane.

A.    Passive transport

Passive transport is transport of ion, molecul, and compound be not needed energy. This transport take place effect from different concentration between zat or solubler. Transport include diffusion. Helped – diffusion, and osmosis.

1.      Diffusion

Diffusion is process random movement particell ( atom, molecul ), gas, fluid, and solubler well exceed or not exceed membrane from high concentration to law concentration until it concentration become same or achieve proportion.

2.      Osmosis

Osmosis is movement solven zat by membrane with help protein transport outstretchely those membrane, protein can’t catalyze a chemist reaction.

B.     Active transport

Active transport is transport be needed energy to movement molecul from one side of membrane to in the other membrane it. Energy be used in cellbis ATP ( Adenosis Tri Phosfat ), that is high energy product from cell respiration, else active transport also need membrane – protein as carry or transportation to through of membrane. Active transport differented become 2, it is ion pump and cotransport.

Ion pump is transport a ion through plasma membrane buck concentration gradient. All cell different potensial energy electric between sitoplasma and area in around it ( membrane potensial ).

Cotransport is transport a zat be actived other transport zat through plasma membrane. Cotransport engage 2 membrane protein.

C.     Endocitosis and exsocitosis

Ø  Endocitosis is happen formation a pouch of cell membrane when a macromolecul be transfered go into membrane. Endocitosis invited become 2 :

1.      Pinocitosis

2.      Fagocitosis

Ø  Exsocitosis is opposite from endocitosis, that is cell secret macromolecul by method add – together vesicula with plasma membrane. In cell eject protein be big total protein beginning assemle in the a pouch be layed membrane in golgy compleks.

2.      Teacher ask students condition.

3.      Teacher take attedance to students.

4.      Teacher give oreintation and aperception “ Mother cook a soup vegetable consist carrots, before salt entered in vegetable the carrots is tasteless but next after salt entered in vegetable the carrots salty. Why the carrots can salty? “

5.      Teacher give motivation to students “ Thereby we will studing transport in the membrane, that’s diffusion and osmosis ”.

B.     Core – activity

·         Exsploration

1.      Teacher explain matter about diffusion and osmosis ( just globally ), just  explain meaning of diffusion and osmosis by speech method with ask variation to students.
