Enzyme

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

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?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the primary function of enzymes?

Back

To speed up reactions by lowering the activation energy.

Front

What happens to enzymes at high temperatures?

Back

They can denature, meaning their shape is altered and they may lose functionality.

Front

What is denaturation in enzymes?

Back

The process where an enzyme's structure is altered, affecting its function.

Front

What is the relationship between enzymes and activation energy?

Back

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

Front

What occurs when an enzyme binds to its substrate?

Back

A temporary enzyme-substrate complex is formed, facilitating the reaction.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.
