Which of the following acts as receptor site on plasma membrane?
Correct answer: D. Glycoprotein
- A. Head of phospholipid molecules
- B. Tail of phospholipid molecules
- C. Cholesterol molecules
- D. Glycoprotein
Explanation
The correct answer is Glycoprotein. Glycoproteins, which are proteins with carbohydrate chains attached, are embedded in the plasma membrane and play a key role as receptor sites. They can recognize and bind to various signaling molecules, including hormones, which initiates cellular responses.
