Front

What happens to enzymes when they are heated to a high temperature?

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where the enzyme's structure is altered, affecting its function.

Front

What factors can affect enzyme activity?
