B.9C Enzymes

Front

What is the definition of a substrate in the context of enzymes?

Back

A substrate is a molecule upon which an enzyme acts.

Front

What is the active site of an enzyme?

Back

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

Front

What happens to an enzyme if its shape changes due to environmental conditions?

Back

If the shape of the enzyme changes, it will no longer be able to catalyze the reaction with the substrate.

Front

What are enzymes primarily composed of?

Back

Enzymes are primarily composed of proteins.

Front

How do enzymes affect the activation energy of a chemical reaction?

Back

Enzymes speed up chemical reactions by lowering the amount of activation energy required to start the reaction.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to increase the rate of biological reactions.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What is denaturation in relation to enzymes?

Back

Denaturation is the process in which an enzyme loses its three-dimensional structure and, consequently, its functionality.
