Question

8 which action might occur when the concentration of sugar molecules is higher outside a cell than inside it? a. sugar molecules flow out of the cell via osmosis. b. passive transport produces more sugar molecules. c. the cell uses channel proteins to produce more sugar molecules. d. some sugar molecules flow into the cell through channel proteins.

Explanation:

Osmosis is the movement of water, not sugar. Passive transport does not produce molecules; it moves them down concentration gradients. Channel proteins facilitate passive transport of sugar from high (outside) to low (inside) concentration.

Answer:

D. Some sugar molecules flow into the cell through channel proteins.
