Question

The diagram models how a poison bonds to the active site of an enzyme. Which function is the enzyme most likely unable to perform because of the attachment of the poison molecule?

A. The catalysis of the reaction with the substrate
B. The release of stored chemical energy
C. The donation of electrons to the substrate
D. The supply of activation energy for a reaction

Answer 1

A. The catalysis of the reaction with the substrate

Step-by-step explanation:

Answer 2

The answer is; A

The active site of the enzyme is bound by a substrate and probably the enzyme catalyzes a hydrolysis reaction. The poison mimics the substrate and competes with the substrate for the active site of the enzyme. The poison may bind permanently to the enzyme rendering the enzyme unavailable for other substrates. This could make a particular biochemical reaction, in which the enzyme is involved, to reduce drastically hence threatening life.
