Enzymes

Front

What happens to enzyme activity when temperatures decrease?

Back

The enzyme slows down.

Front

What is the primary function of an enzyme?

Back

To speed up reactions.

Front

Do allosteric inhibitors block the active site of an enzyme?

Back

False.

Front

What is an inhibitor in the context of enzyme activity?

Back

A substance that can bind to an enzyme and prevent the substrate from binding.

Front

What does a substrate become after it binds with an enzyme and undergoes a reaction?

Back

Product(s).

Front

What is the role of the active site in an enzyme?

Back

It is the region where the substrate binds and the reaction occurs.

Front

What is the effect of pH on enzyme activity?

Back

Enzymes have optimal pH levels; deviations can reduce activity.

Front

What are cofactors and coenzymes?

Back

Cofactors are non-protein molecules that assist enzymes; coenzymes are organic cofactors.

Front

What is enzyme specificity?

Back

The ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

How do competitive inhibitors affect enzyme activity?

Back

They compete with the substrate for the active site, reducing the rate of reaction.
