In which process is energy required but not directly used to produce movements against concentration gradients?
A) osmosis
B) primary active transport
C) secondary active transport
D) simple diffusion
E) facilitated diffusion

Question

Quizplus · Accepted Answer

Secondary active transport requires energy in the form of an electrochemical gradient established by primary active transport, but this energy is not directly used to produce movements against concentration gradients. Osmosis, simple diffusion, and facilitated diffusion do not require energy, while primary active transport directly uses energy to create movement against a concentration gradient.
