Enzymes

Front

What is an enzyme?

Back

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

Front

What is a substrate?

Back

Any substance that is acted upon by an enzyme.

Front

What is the active site of an enzyme?

Back

The specific region on the enzyme where the substrate binds.

Front

What are products in an enzyme-catalyzed reaction?

Back

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

Front

What is the enzyme-substrate complex?

Back

The temporary complex formed when an enzyme binds to its substrate.

Front

What does it mean for an enzyme to be specific?

Back

Enzymes are specific to particular substrates and catalyze specific reactions.

Front

What is the lock and key model?

Back

A model that explains how enzymes and substrates fit together perfectly, like a key in a lock.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and concentration of substrate or enzyme.

Front

What is denaturation in relation to enzymes?

Back

The process where an enzyme loses its shape and functionality due to extreme conditions.

Front

What role do coenzymes play in enzyme activity?

Back

Coenzymes are non-protein molecules that assist enzymes in catalyzing reactions.
