If the metabolism of a cell suddenly slowed down so that there was less cellular energy available, which role of the cell membrane would you expect to be most affected?

a. the active transport of ions across the membrane
b. the facilitated diffusion of sugars
c. the osmosis of water across the membrane
d. the passive diffusion of oxygen across the membrane

With less cellular energy available, you would inhibit processes that require ATP.

B, C, and D all are processes that are passive - and involve concentration gradients.

Only A needs ATP to function.
