Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the optimal temperature for enzymes?

Back

The optimal temperature is the temperature at which an enzyme's activity is highest.

Front

What is the optimal pH for enzymes?

Back

The optimal pH is the pH level at which an enzyme functions most effectively.

Front

What role do enzymes play in chemical reactions?

Back

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

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds.

Front

What is a substrate?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What happens to an enzyme after a reaction?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme.
