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.
Genotype is not the only thing that effect phenotype because you have environment effects as well that can cause a vary of things.....
<span>Active transport works to conserve homeostasis. When cells are doing something they typically receive a signal causing channels to open, which in turn lets in a flood of molecules down their chemical gradients. Hope this answers the question.</span>
