B)Receptor sites are made of glucose.

Question

Quizplus · Accepted Answer

A) Cholesterol is a crucial component of the cell membrane, providing stability and preventing excessive fluidity.
C) The cell membrane is selectively permeable, meaning it regulates what and how much of a substance can cross the membrane.
F) Receptor sites on the cell membrane are important for communication between cells and allow for the recognition of specific molecules or signals. Glucose is not a component of receptor sites. Phospholipids, on the other hand, are a critical component of the cell membrane and are always present. Microvilli are extensions of the cell membrane that increase surface area and are not involved in sweeping materials across the cell surface.
