Question

which of the following components of the cell membrane is responsible for active transport? phosphate cholesterol protein lipid phospholipid multiple choice 1 point

Explanation:

Proteins in the cell - membrane are responsible for active transport. They act as pumps or carriers to move substances against their concentration gradient, requiring energy input. Phosphates are part of phospholipids but not directly for active transport. Cholesterol helps with membrane fluidity. Lipids form the basic structure of the membrane but don't perform active - transport functions. Phospholipids create the lipid bilayer of the membrane.

Answer:

C. Protein
