What happens to reaction rate if temperatures decrease?

Back

Decrease

Front

What is an inhibitor that binds to the active site of an enzyme?

Back

Competitive inhibitor

Front

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

Back

Reaction rate decreases

Front

Which describes an endergonic reaction?

Back

Positive ΔG, nonspontaneous

Front

What does the second law of thermodynamics state about disorder?

Back

Every reaction increases the entropy

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up reactions by lowering activation energy.

Front

Define activation energy.

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the difference between competitive and noncompetitive inhibitors?

Back

Competitive inhibitors bind to the active site, while noncompetitive inhibitors bind to another part of the enzyme.

Front

What is the significance of ΔG in thermodynamics?

Back

ΔG indicates the spontaneity of a reaction; negative ΔG means spontaneous, positive ΔG means nonspontaneous.

Front

Explain the concept of entropy.

Back

Entropy is a measure of disorder or randomness in a system.
