Describe the cycle of an enzyme as it catalyzes a reaction.

Answer: Enzyme bind to the substrate and increase the reaction rate so catalyze a reaction.

Explanation: Enzymes are the protein molecules and act as a catalyst for a reaction. Enzymes bind to the substrate. A substrate is the reactant molecule of a reaction.

The cycle of enzyme catalysis reaction is as follows:

1. Cycle starts with the binding of enzyme to the substrate, binding takes place at the active site of enzyme.

2. When substrate perfectly fits in active site of enzyme, the binding of enzyme and substrate results in the formation of enzyme-substrate complex.

3. As result of which final product is formed at the end of the reaction.
