Membrane proteins serve many functions, one of which is transportation of substances across a membrane. if a cytologist placed cells into an environment where a chemical blocks the function of carrier proteins, which process will be affected?

facilitated diffusion

Explanation: facilitated diffusion us the carrier-mediated Transport of large molecules across the cell membrane using Transport proteins found in the cell membrane.such molecules include glucose,amino acids and ions.the passage across the membrane is from higher concentration to lower concentration

i believe the correct answer is d
