Enzyme Practice

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts to speed up chemical reactions in the body.

Front

What happens to enzymes at high temperatures or extreme pH levels?

Back

Enzymes can become denatured, meaning they lose their functional shape and activity.

Front

What is the term for the molecule that binds to an enzyme's active site?

Back

The substrate.

Front

Can enzymes be used more than once in a chemical reaction?

Back

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

Front

What is the role of an enzyme in a chemical reaction?

Back

An enzyme speeds up the rate of a chemical reaction without being consumed in the process.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure due to external factors like heat or pH, resulting in loss of function.

Front

What is the active site of an enzyme?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme by binding to it.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to a different site on the enzyme.
