Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

How does the shape of an enzyme relate to its function?

Back

The enzyme is shaped specially for certain substrates to perform a specific reaction.

Front

What is activation energy?

Back

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

Front

How do enzymes affect activation energy?

Back

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

Front

What happens to an enzyme when it denatures?

Back

When an enzyme denatures, it loses its specific shape, which affects its ability to function.

Front

What factors can cause an enzyme to denature?

Back

Changes in pH and temperature can cause an enzyme to denature.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after a reaction.

Front

What is a substrate?

Back

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

Front

What is the active site of an enzyme?

Back

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