HB Midterm Enzymes Review

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What is the function of catalase?

Back

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds and the reaction occurs.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What does optimum pH mean in relation to enzymes?

Back

Optimum pH is the pH level at which an enzyme's activity is at its maximum.

Front

How do enzymes affect activation energy?

Back

Enzymes decrease the activation energy needed for a reaction, making it easier for the reaction to occur.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What are products in a chemical reaction?

Back

The substances that are produced as a result of a chemical reaction.

Front

What happens to enzymes after a reaction?

Back

Enzymes are not consumed in the reaction and can be reused multiple times.

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction or acts on a specific substrate.
