Which statement would be true of a membrane-bound protein that works in conjunction with a sodium–potassium pump during secondar
Rudik [331]

Answer:

The correct answer is option d. "Its conformation will change when both an ion and a small molecule bind to it".

Explanation:

The secondary active transport is a form of active transport at which a ion (typically Na+ or H+)  is transferred down its electrochemical gradient to the uphill movement of another molecule. Secondary active transport takes place by the conjunctive work of membrane-bound proteins and sodium–potassium pumps. During secondary active transport, both of these proteins change its conformation when an ion and a small molecule bind to it. This change in conformation makes possible that the ions and the small molecules pass through the membrane.
