Enzymes - How Do They Work?

Front

What is an enzyme?

Back

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

Front

What role do enzymes play in chemical reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What are products in a chemical reaction?

Back

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

Front

How do enzymes affect the rate of reactions?

Back

Enzymes increase the rate of reactions, allowing them to occur more quickly.

Front

What is the active site of an enzyme?

Back

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

Front

What happens to an enzyme after a reaction?

Back

The enzyme is not consumed in the reaction and can be reused for subsequent reactions.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.

Front

What is denaturation in relation to enzymes?

Back

Denaturation is the process where an enzyme loses its shape and functionality due to extreme conditions.

Front

What is the lock and key model of enzyme action?

Back

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