Front

Define enzyme.

Back

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

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its shape and function due to external factors like heat or pH.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What is an exothermic reaction?

Back

A reaction that releases energy, usually in the form of heat.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from its surroundings.
