Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.

Front

Where do substrates bind on an enzyme?

Back

Substrates bind at the active site of an enzyme.

Front

What suffix do most enzymes end with?

Back

Most enzymes typically end with the suffix -ase.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is highest; for some enzymes, this can be around 6.6.

Front

What is another name for enzymes?

Back

Enzymes are also known as biological catalysts.

Front

What role do enzymes play in biological reactions?

Back

Enzymes lower the activation energy required for reactions, allowing them to occur more easily and quickly.

Front

Can enzymes be reused after a reaction?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors such as temperature, pH, and substrate concentration can affect enzyme activity.

Front

What happens to an enzyme when it denatures?

Back

When an enzyme denatures, it loses its specific shape and, consequently, its ability to function.

Front

What is a substrate in the context of enzymes?

Back

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