Front

What is the process of changing the molecular conformation of a protein to destroy its function?

Back

Front

What happens to an enzyme when it is denatured?

Back

It loses its shape.

Front

What are proteins that act as biological catalysts by speeding up chemical reactions?

Back

Enzymes

Front

What is the measure of acidity in a substance?

Back

pH

Front

What is the term for the site on an enzyme where the substrate binds?

Back

Active site

Front

What is the role of a coenzyme in enzyme activity?

Back

Coenzymes assist enzymes in catalyzing reactions.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is a substrate in the context of enzyme activity?

Back

The substance upon which an enzyme acts.

Front

What effect does temperature have on enzyme activity?

Back

Enzymes typically have an optimal temperature range; too high or too low can denature them.

Front

What is the relationship between enzymes and catalysts?

Back

Enzymes are a type of catalyst that speed up biochemical reactions.
