Enzymes

Front

What is an enzyme?

Back

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

Front

What are the main components of an enzyme?

Back

Enzymes are primarily made of proteins.

Front

What is the active site of an enzyme?

Back

The specific region on the enzyme where the substrate binds.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What are products in an enzymatic reaction?

Back

The substances that are produced as a result of the enzymatic reaction.

Front

What factors affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

At what temperature do most enzymes work best?

Back

Most enzymes work best at around 37°C, but this can vary.

Front

What happens to an enzyme when it denatures?

Back

It loses its shape and, consequently, its ability to function.

Front

What is enzyme specificity?

Back

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

Front

What role do coenzymes play in enzyme activity?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions.
