Enzymes Review

Front

What is an enzyme?

Back

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

Front

What is the optimal temperature range for most enzymes?

Back

Typically around 30°C to 40°C, but it can vary depending on the specific enzyme.

Front

What happens to enzymes at high temperatures?

Back

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

Front

What is a catalyst?

Back

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

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its three-dimensional structure due to external factors like temperature or pH.

Front

What is the active site of an enzyme?

Back

The specific region where substrate molecules bind and undergo a chemical reaction.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to denaturation and loss of activity.

Front

Can enzymes be reused?

Back

Yes, enzymes can be reused multiple times in chemical reactions.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon to facilitate a chemical reaction.

Front

What is the effect of extreme pH on enzymes?

Back

Extreme pH can denature enzymes, rendering them inactive.
