The Enzyme Glucose Oxidase Binds the Six-Carbon Sugar Glucose and Catalyzes

Multiple Choice

The enzyme glucose oxidase binds the six-carbon sugar glucose and catalyzes its conversion to glucono-1,4-actone. Mannose is also a six-carbon sugar, but glucose oxidase cannot bind mannose. The specificity of glucose oxidase is based on the

A) free energy of the transition state.
B) activation energy of the reaction.
C) change in free energy of the reaction.
D) three-dimensional shape and structure of the active site.
E) rate constant of the reaction.
