Active and passive transports across cell membrane differ in

A. Passive transport is along the concentration

B. Passive transport is along the concentration gradient while active transport is due to metabolic energy

C. Active transport is more rapid

D. Passive transport is confined to anions while active transport in confined to cations

Answer: Option B

Solution(By Examveda Team)

Active and passive transports across cell membranes differ in Passive transport is along the concentration gradient while active transport is due to metabolic energy.
Active transport is the process of moving molecules across a cellular membrane through the use of cellular energy.
Passive transport is a type of cellular transport in which substances such as ions and molecules move down their respective concentration gradients. It does not require energy input.
