Protein layers which are NOT continuous on the surface make _ percent of total in plasma membrane.
Correct answer: C. 60 - 80
- A. 50 - 60
- B. 60 - 70
- C. 60 - 80
- D. 70 - 80
- E. 70 - 90
Explanation
The plasma membrane is composed of lipids, proteins, and carbohydrates. Proteins play an important role in the structure and function of the membrane, including transport of molecules, cell recognition, and communication between cells. The protein layers on the surface of the plasma membrane are not continuous, and they make up approximately 60-80% of the total proteins in the membrane. Option C, 60-80%, is the correct answer.
