Question

What statement best describes what happens during the catalytic cycle?
A The enzyme breaks the substrate apart to prepare for the reaction.
B The enzyme positions the substrate to increase access during a reaction.
C The substrate uses enzyme energy to start the reaction.
D The active site releases the substrate and replaces it with an inhibitor.

Answer 1

Answer is b

\\\_/// good luck

Answer 2

Answer:

B. The enzyme positions the substrate to increase access during a reaction.

Explanation:

The catalytic cycle is, in chemistry, a reaction mechanism caused by an enzyme, and this method is characterized by sequences of chemical reactions.

In the catalytic cycle, the first reaction involves the binding of one or more substrates by the enzyme, and the interaction of the elements provides the chemical reactions. The enzyme positions the substrate to increase access during a reaction. In this cycle, the activation energy exceeds the repulsion force, being responsible for the collisions and breakdowns of the reagents. Using catalysts, the equilibrium of reactions is achieved faster.
