Enzymes

Front

What is the role of an enzyme in a chemical reaction?

Back

An enzyme speeds up a reaction by lowering the activation energy.

Front

What type of reaction releases energy?

Back

An exothermic reaction releases energy.

Front

What are substances that are changed during a chemical reaction called?

Back

Reactants are the substances that are changed during a chemical reaction.

Front

What term describes the specificity of enzymes for their substrates?

Back

Specificity refers to the fact that each enzyme only has one substrate that will fit its active site.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What are the products of a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the difference between reactants and products?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed at the end.

Front

What is meant by enzyme specificity?

Back

Enzyme specificity means that each enzyme is designed to catalyze a specific reaction with a specific substrate.

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.
