Passive membrane transport processes include ________.

Question

Quizplus · Accepted Answer

Passive transport processes do not require energy expenditure, and movement down a concentration gradient is the hallmark of passive transport.

Answer: B 
 This describes osmosis, a type of passive transport where water moves from an area of high solute concentration to an area of low solute concentration.

Answer: C 
 Active transport processes require energy expenditure, not passive transport processes.

Answer: D 
 This describes active transport, not passive transport. Passive transport moves substances with their concentration gradient, while active transport requires the use of energy to move substances against their concentration gradient.
