Primary active ABC transporters and P-type transporters both require
A) a conformational change to function.
B) two ATP binding half-sites.
C) solutes that move down their concentration gradients through the transporter.
D) removal of inhibitory subunits to function.

Question

Quizplus · Accepted Answer

Both primary active ABC transporters and P-type transporters require a conformational change in order to function properly. This is because they use ATP hydrolysis to power the movement of molecules across a membrane, which requires a change in shape of the transporter protein. Choices B, C, and D are not accurate for both types of transporters.
