One reason the proximity effect enhances catalysis is because
A)the effective molarity of reactive substrate groups increases.
B)the enzyme changes conformation to more readily accept the substrate as it approaches the active site.
C)the active site becomes smaller.
D)the catalytic triad in the active site becomes more flexible.

Question

Quizplus · Accepted Answer

The proximity effect refers to the increased concentration of reactive groups, such as substrates or functional groups, in close proximity to each other. This increases the effective molarity of these groups, which enhances catalysis by increasing the frequency of their collisions and therefore increasing the likelihood of their reaction.
