Which is not a similarity between active transport proteins and enzymes?
A)Both undergo conformational changes upon binding a substrate.
B)Both are susceptible to inhibition.
C)Both cause chemical modification to the substrate.
D)Both can reach a saturation limit.

Quizplus · Accepted Answer

Active transport proteins do not cause chemical modification to the substrate. Enzymes catalyze chemical reactions by modifying the substrate, while active transport proteins move molecules across biological membranes against their concentration gradients, without modifying them. A similarity between both types of proteins is that they undergo conformational changes upon binding a substrate, they can be inhibited, and they can reach a saturation limit.
