Membrane proteins serve many functions.One of the functions is transportation of substances across the membrane.If a cell biologist placed cells into an environment in which a chemical has been added that blocks the function of only carrier proteins,the process that will be affected is
A)active transport.
B)osmosis.
C)simple diffusion.
D)phagocytosis.
E)pinocytosis.

Question

Quizplus · Accepted Answer

Carrier proteins are involved in active transport, which requires the use of energy to transport substances against their concentration gradient. Osmosis, simple diffusion, phagocytosis, and pinocytosis do not require carrier proteins and are not affected by their inhibition.
