8I: Enzyme Activity and Factors Flashcard

Front

What happens to an enzyme when it is denatured?

Back

It loses its shape and function.

Front

Why can extreme pH levels denature an enzyme?

Back

They alter the enzyme's active site.

Front

What is the specific region of an enzyme where a substrate binds called?

Back

Active site.

Front

How does a non-competitive inhibitor affect enzyme activity?

Back

It changes the shape of the enzyme.

Front

What are the optimal conditions for enzyme activity?

Back

Conditions that allow the enzyme to function at its highest efficiency.

Front

Define enzyme denaturation.

Back

The process in which an enzyme loses its three-dimensional structure, leading to a loss of function.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and inhibitors.

Front

What is the role of an enzyme's active site?

Back

It is the region where substrates bind and undergo a chemical reaction.

Front

What is a competitive inhibitor?

Back

A substance that competes with the substrate for binding to the active site of an enzyme.

Front

How does temperature affect enzyme activity?

Back

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