Which helps ensure the diffusion of glucose into a cell that has a high energy need?
A) A glucose pump
B) Ion channels found in large muscle cells
C) A high number of carrier proteins specific for glucose
D) An extracellular environment high in glucose
E) Additional pores through which water can flow, carrying dissolved glucose

Question

Quizplus · Accepted Answer

The presence of a high number of carrier proteins specific for glucose helps ensure the diffusion of glucose into a cell that has a high energy need, such as muscle cells during exercise. These carrier proteins are able to bind with glucose molecules and facilitate their movement across the cell membrane.
