AP - Unit 3: Metabolism, Energy and Enzymes

Front

What is an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that releases energy, often in the form of heat.

Front

What happens to heat in an exergonic reaction?

Back

Heat is released.

Front

What is the role of a substrate in enzymatic reactions?

Back

The substrate is the molecule upon which an enzyme acts.

Front

What are enzymes primarily made of?

Back

Enzymes are primarily made of proteins.

Front

How do non-competitive inhibitors affect enzyme activity?

Back

Non-competitive inhibitors change the shape of the enzyme, reducing its activity.

Front

What is the most important factor that determines an enzyme's function?

Back

The shape of the enzyme is the most important factor that determines its function.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site of the enzyme, while non-competitive inhibitors bind to a different site, changing the enzyme's shape.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction, increasing the reaction rate.

Front

What is the active site of an enzyme?

Back

The active site is the region of the enzyme where substrate molecules bind and undergo a chemical reaction.
