Question

2 multiple choice 1 point which of the following is an example of passive transport? endocytosis exocytosis facilitated diffusion sodium - potassium pump

Explanation:

Passive transport is a type of cellular transport that does not require energy input. Facilitated diffusion is a form of passive transport where molecules move across the cell membrane with the help of transport proteins down their concentration gradient. Endocytosis and exocytosis are forms of active transport that require energy and involve the cell membrane forming vesicles. The sodium - potassium pump is also an active transport mechanism as it uses energy (ATP) to move sodium and potassium ions against their concentration gradients.

Answer:

C. Facilitated diffusion
