Enzymes

Front

What is an enzyme?

Back

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

Front

What is a substrate?

Back

The specific reactant that an enzyme acts upon in a chemical reaction.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds and the reaction occurs.

Front

What are products in a chemical reaction?

Back

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

Front

What are reactants in a chemical reaction?

Back

The starting materials that undergo change during a chemical reaction.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, thus speeding it up.

Front

What is the relationship between enzymes and substrates?

Back

Enzymes are specific to their substrates, meaning each enzyme only catalyzes a specific reaction.

Front

What is a coenzyme?

Back

A non-protein molecule that assists enzymes in catalyzing reactions.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can reduce their activity or denature them.

Front

What is enzyme denaturation?

Back

The process in which an enzyme loses its functional shape due to extreme conditions, rendering it inactive.
