Front

What is an enzyme?

Back

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

Front

What does it mean for an enzyme to be 'recycled'?

Back

Enzymes are not consumed in a reaction; they can be used repeatedly to catalyze multiple reactions.

Front

What is the optimal pH for enzyme A?

Back

The optimal pH for enzyme A is 2.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What happens to enzyme activity at extreme temperatures?

Back

Extreme temperatures can denature enzymes, leading to a loss of function.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature for enzyme activity varies, but for the enzyme in the provided question, it is 30°C.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed for a reaction, making it easier for the reaction to occur.

Front

What is specificity in relation to enzymes?

Back

Specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Front

What is a substrate?

Back

The reactant molecule upon which an enzyme acts.
