Most of the functions of a cell membrane are performed by _. proteins. cholesterol. None of these. glycolipids. Select all of the groups of membrane proteins: Lipid-anchored 21 Integral Peripheral What kind of what type of membrane protein is shown in Figure 4.13 below? This is a type of protein.

Solution

1. Proteins
Main function of Cell membrane are, 1.structural and protection of cells and 2. Selective permeability of ions passes from into or out of the cells. Proteins plays a major role in selective permeability.

Glycolipids are carbohydrates molecule attach to phopholipids. It acts as marker and communication role.

In animal cells of plasma menbrane Cholestrol palys a major role in fluidity.

12. Intergal and peripheral protein
Intergal membrane are permanent protein present in the membrane. It helps in channels, in transduction of signals, receptors etc.
Peripheral membrane protein are temporary present on the membrane.

13. Both are alpha helical and Intergal protein.
1. Single alpha helical transmembrane protein
2. Polytopic alpha helical transmembrane protein
