A ) Phospholipids are fluid and can move throughout the membrane. B)Phospholipids heads are negative and attracted to water.
C ) Protein receptors are found on the exterior of the cell only.
D )Carbohydrates are useful in cell communication.

Answer 1

The statement that is not true about the cell membrane is option C) Protein receptors are found on the exterior of the cell only.

Step-by-step explanation:

The statement that is not true about the cell membrane is option C) Protein receptors are found on the exterior of the cell only.

The cell membrane is composed of two adjacent layers of phospholipids, with their hydrophobic tails facing each other in the inner region of the membrane. The phospholipid heads face outward, with one layer exposed to the interior of the cell and the other layer exposed to the exterior. Both sides of the cell membrane contain proteins, including protein receptors that are involved in cell signaling and communication.
