Question

which of the following is not a function of membrane proteins?
bind to ligands
store cellular nutrients
act as carrier molecules for various solutes
regulate the passage of ions
act as anchors or stabilizers for the cell membrane

Explanation:

• Membrane proteins have various functions: Receptor proteins bind to ligands (e.g., hormones). Carrier proteins (like ion channels or transporters) act as carriers for solutes and regulate ion passage. Structural proteins act as anchors/stabilizers for the cell membrane.
• Storing cellular nutrients is not a function of membrane proteins. Nutrient storage is typically done by molecules like glycogen (in cells) or lipids, not membrane proteins.

Answer:

B. store cellular nutrients
