Enzymes

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes decrease the activation energy of reactions, thereby speeding up the rate of the reaction.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature for enzyme activity varies by enzyme, but in this case, it is 30°C.

Front

True or False: Enzymes can only be used once in a chemical reaction.

Back

False. Enzymes can be used multiple times as they are not consumed in the reaction.

Front

What term describes the ability of an enzyme to only bind to a specific substrate?

Back

Specificity.

Front

Which of the following is an example of an enzyme? Amylase, Glucose, or Water?

Back

Amylase.

Front

What is activation energy?

Back

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

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy required for the reaction to proceed.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can catalyze subsequent reactions.

Front

What factors can affect enzyme activity?

Back

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