AP Biology Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.

Front

Do enzymes act on many different substrates?

Back

False. Enzymes are specific to their substrates.

Front

What happens to enzymes at high temperatures?

Back

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

Front

What is an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that proceeds with a net release of free energy.

Front

What role do vitamins and minerals play in enzyme activity?

Back

Vitamins and minerals act as activators, helping enzymes function properly.

Front

Can enzymes be used more than once in chemical reactions?

Back

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

Front

What is the effect of extreme pH on enzymes?

Back

Extreme pH can denature enzymes, altering their shape and function.

Front

What is the difference between an enzyme and a substrate?

Back

An enzyme is a catalyst that speeds up reactions, while a substrate is the substance upon which an enzyme acts.

Front

What is the active site of an enzyme?

Back

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

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.
