MC ENZYMES AND BIOCHEM

Front

What is an endothermic reaction?

Back

A type of reaction that absorbs energy from its surroundings.

Front

What is an exothermic reaction?

Back

A type of reaction that releases energy to its surroundings.

Front

What are enzymes?

Back

Proteins that speed up biochemical reactions by lowering the activation energy.

Front

What happens to enzymes at high temperatures?

Back

They denature, meaning they change shape and lose their functionality.

Front

What is the active site of an enzyme?

Back

The specific region on an enzyme where the substrate binds.

Front

What is a substrate in the context of enzymes?

Back

The reactant molecule that an enzyme acts upon.

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its three-dimensional structure and functionality due to external stress, such as heat.

Front

What is the role of temperature in enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low can reduce their activity.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is metabolism?

Back

The sum of all chemical reactions that occur within a living organism.
