Question

Which of the following is not true about the cell membrane? Protein receptors are found on the exterior of the cell only. Phospholipids heads are negative and attracted to water. Carbohydrates are useful in cell communication. Phospholipids are fluid and can move throughout the membrane.

Answer 1

Protein receptors are found on the exterior of the cell only

Step-by-step explanation:

The statement "Protein receptors are found on the exterior of the cell only" is not true about the cell membrane. Protein receptors are found on both the exterior and interior surfaces of the cell membrane. These receptors play a crucial role in cell communication and signal transduction, and they can interact with signaling molecules both outside and inside the cell.
