AP Bio Insta-Review Topic 3.3: Environmental Impacts on Enzyme

Front

What happens to the reaction rate if the enzyme is denatured?

Back

The reaction rate decreases.

Front

Which structure of an enzyme is not affected when it denatures?

Back

Primary structure.

Front

Why does an enzyme denature when pH increases?

Back

pH affects the charged R groups.

Front

True or False: A decrease in temperature will denature an enzyme.

Back

False.

Front

What is a competitive inhibitor?

Back

A substance that binds to the same site as the substrate.

Front

What is enzyme denaturation?

Back

The process where an enzyme loses its functional shape.

Front

What factors can lead to enzyme denaturation?

Back

High temperature, extreme pH, and high salt concentrations.

Front

What is the primary structure of a protein?

Back

The sequence of amino acids in a polypeptide chain.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases reaction rates until denaturation occurs.

Front

What is the role of R groups in enzymes?

Back

R groups determine the properties and functions of amino acids in the enzyme.
