Question

9 multiple choice 10 points which of the following components of the cell membrane is responsible for active transport? phospholipid protein lipid cholesterol

Explanation:

Active transport requires energy and specific membrane - spanning proteins (carrier proteins or pumps) to move substances against their concentration gradient. Phospholipids form the basic structure of the membrane (lipid bilayer). Lipids (including phospholipids and cholesterol) mainly contribute to membrane fluidity and structure. Cholesterol modulates membrane fluidity. Proteins, on the other hand, can act as carriers or pumps in active transport.

Answer:

Protein
