Question

1.How does cholesterol control the movement of the cell membrane in cold and warmth?

2.What kind of proteins are in the cell membrane?
3.What can go through cell membranes?

4.What does cholesterol do in the cell membrane?

5.What does saturation do to the phospholipids

6.Are phospholipids still in the cell membrane?

7.What keeps cells moving in cold weather?

Answer 1

1). Cholesterol interacts with phospholipids in cold conditions and prevent them from stiffening or clustering. Where as at high temperatures i sabilizes the cell membrane.

2). There are peripheral proteins,integral proteins,glycolipoproteins and phospholipoproteins in cell membrane.

3).cell membrane is asemipermeable membrane which acts a passage to number of ions,electrons,glucose molecules..etc.

4). Cholesterol slightly immobilizes the outersurface of the cell membrane. without cholesterol cell membrane will be too fluid in nature.
