Enzyme Review

Front

What is an enzyme?

Back

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

Front

What is the optimal temperature for enzyme activity?

Back

The temperature at which an enzyme functions most efficiently, often around 30°C for many enzymes.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the difference between catabolic and anabolic reactions?

Back

Catabolic reactions break down molecules into smaller units, while anabolic reactions build larger molecules from smaller units.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape is altered, which affects their function.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What is a product in enzymatic reactions?

Back

The molecules that are produced as a result of the enzymatic reaction.

Front

What is denaturation?

Back

The process in which an enzyme loses its functional shape due to external stress, such as high temperature or extreme pH.

Front

How do enzymes speed up reactions?

Back

By lowering the activation energy required for the reaction to occur.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where the substrate binds and the reaction occurs.
