Which of the following contributes to the ability of lipids and proteins to move

Question

Which of the following contributes to the ability of lipids and proteins to move laterally within membranes (choose all that apply)?

Question 10 options:

A)

Hydrophilic portions of the lipids are in the interior of the membrane.

B)

The individual intermolecular interactions in the membrane are noncovalent and weak.

C)

The intermolecular interactions in the membrane are covalent and strong.

D)

Proteins and lipids in the membrane can diffuse.

E)

Lipids and proteins repel each other in the membrane.

Explanation / Answer

ans)

Hydrophilic portions of the lipids are in the interior of the membrane - These statement is not correct option. Hence option A is wrong.

explanation: Hydrophilic portions is present at the surface of the membrane

The individual intermolecular interactions in the membrane are noncovalent and weak - These statement is correct. Hence option B is correct.

Explanation: noncovalent and weak like electrostatic interaction , van dar wal interactions leads to lateral movement is possible for proteins and lipids

The intermolecular interactions in the membrane are covalent and strong- These statement is incorrect. Hence option C is incorrect.

Proteins and lipids in the membrane can diffuse- These statement is incorrect . Hence option D is incorrect

Lipids and proteins repel each other in the membrane- These statement is incorrect. Hence option E is incorrect.
