In active transport,the affinity of any given binding site for the molecule to be transported changes as the site goes from facing one side of the membrane to facing the other side.

Question

Quizplus · Accepted Answer

This statement is true. Active transport involves the movement of molecules against their concentration gradient, which requires the use of energy and specialized transport proteins that undergo conformational changes to move the molecule from one side of the membrane to the other. These transport proteins typically have binding sites that exhibit different affinities for the transported molecule in different conformations, allowing for the translocation of the molecule across the membrane.
