Why do metabolic pathways require tens to hundreds of different enzymes?
A) The enzymes are used up after one reaction and the molecules have to undergo multiple rearrangements.
B) The enzyme is deformed by the interaction with the substrate and needs a period of time to return to its original reactive form, so many enzymes are needed to keep the pathway going.
C) Each enzyme has a specific substrate and produces a specific product.
D) Multiple enzymes are not required for the pathway, but having them speed up the production of the final product.
E) The enzymes are attached to a membrane and cannot move to the location of the new intermediate, so having a long line of enzymes to carry out the reaction allows the reaction to occur faster.

Question

Quizplus · Accepted Answer

Each enzyme in a metabolic pathway is specialized to catalyze a specific reaction, converting a specific substrate into a specific product. This specificity is crucial for the orderly and efficient progression of metabolic processes, where each step is catalyzed by a different enzyme tailored to that reaction.
