The Maximum Rate of an Enzyme Reaction

Question

The maximum rate of an enzyme reaction
A) occurs during dehydration.
B) occurs during hydrolysis.
C) occurs during synthesis.
D) is reversible.
E) occurs at the saturation limit.

Accepted Answer

The maximum rate of an enzyme reaction occurs at the saturation limit, when all available enzyme active sites are bound to substrate molecules. Any further increase in substrate concentration will not increase the rate of reaction beyond the maximum rate, as the enzyme is working at full capacity.
