What is the membrane property that helps ensure the diffusion of glucose into a cell that has a high energy need?
A) A glucose pump
B) Specific carrier proteins found only in large muscle cells
C) A high number of carrier proteins specific for glucose
D) Special sensitivity to an extracellular environment high in glucose
E) Additional pores through which water can flow,carrying dissolved glucose

Question

Quizplus · Accepted Answer

A high number of carrier proteins specific for glucose would increase the likelihood of glucose molecules diffusing into the cell, which is important for cells with high energy needs, such as muscle cells. A glucose pump is not a membrane property, specific carrier proteins for glucose are not found only in large muscle cells, special sensitivity to an extracellular environment high in glucose is not a membrane property, and additional pores through which water can flow are not specific to glucose and would not ensure its diffusion into the cell.
