Which of the following statements most accurately compares primary factors responsible for simple diffusion versus active transport?
A) Simple diffusion is driven by a concentration gradient, while active transport is driven by ADP.
B) Simple diffusion is driven by a concentration gradient, while active transport is driven by ATP hydrolysis.
C) Simple diffusion is driven by ATP hydrolysis, while active transport is driven by an electrochemical gradient.
D) Simple diffusion is driven transmembrane pumps, while active transport is driven by ATP hydrolysis.

Question

Quizplus · Accepted Answer

Simple diffusion relies on the natural movement of molecules from an area of higher concentration to an area of lower concentration without the need for energy. Active transport, on the other hand, requires energy in the form of ATP hydrolysis to move molecules against their concentration gradient.
