If active transport establishes a concentration gradient with the use of ATP, then the concentration gradient can be looked at as_________ .
A) an unusable byproduct of active transport that will simply diffuse away
B) a byproduct of active transport that will be alleviated by pinocytosis
C) unwanted pressure that will be alleviated by channel mediated facilitated diffusion
D) potential energy that can be harnessed when molecules passively diffuse down the concentration gradient

Question

Quizplus · Accepted Answer

The concentration gradient established by active transport is a form of potential energy that can be harnessed when molecules passively diffuse down the gradient. This is the driving force behind facilitated diffusion and allows cells to use the energy from ATP to move molecules against their concentration gradient, ultimately maintaining homeostasis.
