1. Which of the following does NOT describe a mechanism that cells use to regulate enzyme
activities? Cells control enzyme activity by phosphorylation and dephosphorylation of the
enzyme Cells control enzyme activity by the binding of small molecules to regulatory sites on
an enzyme Cells control the rates of diffusion of substrates to enzymes Cells control the rates of
enzyme degradation Cells control the rates of enzyme synthesis Cells control the targeting of
enzymes to specific organelles
Solution
The false statement is that cells control the rate of diffusion of substrates to enzymes.
The mechanisms that regulate enzyme activities include-
