Understanding Enzymes and Reactions

Front

What is activation energy?

Back

The energy required to start a reaction.

Front

What happens to an enzyme when it is denatured?

Back

It loses its specific shape and function.

Front

What is a non-competitive inhibitor?

Back

A molecule that binds to a site other than the active site, altering enzyme function.

Front

What is the effect of a competitive inhibitor on enzyme activity?

Back

It binds to the active site, preventing substrate binding.

Front

Which factor does NOT affect enzyme activity?

Back

Color of the enzyme.

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature generally increases enzyme activity up to a certain point, after which denaturation occurs.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region of the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction or type of reaction.

Front

What are cofactors and coenzymes?

Back

Cofactors are non-protein molecules that assist enzymes, while coenzymes are organic molecules that serve as cofactors.
