LESSON 3c: CELL MEMBRANE

Question 1

Composed of phospholipid bilayer, and also exhibits the fluid mosaic model.

Answer 1

Cell membrane

Question 1

A thin membrane around the cell that act as a barrier and, separates inner and outer cell area.

Answer 1

Cell membrane

Question 2

What is the function of Cell membrane

Answer 2

Semi-permeable, protein anchor, and energy conservation.

Question 3

The act of transporting elements in and out the cell.

Answer 3

Cell membrane transport

Question 4

A type of cell membrane transport that does not use ATP, and moves element across concentration gradient (High to low concentration).

Answer 4

Passive transport

Question 5

what are the types of passive transport?

Answer 5

Osmosis - net movement of water
Simple diffusion - moves small element
facilitated diffusion - moves large element

Question 6

What are the types of active transport

Answer 6

Simple transport - moves small element driven by PMF

ABC transport - 3 components: binding protein, transport and atp-hydrolyzing protein

Group translocation - Employs series of proteins.

Question 7

A type of cell membrane transport that uses ATP, and moves elements and nutrients against concentration gradient (low to high concentration.

Answer 7

Active transport
