Unit 3: Energy Flow Test 1 Review

Front

What is an exothermic reaction?

Back

A reaction that releases more energy than it absorbs.

Front

What reaction directly provides chemical energy for most cell functions?

Back

ATP --> ADP + P

Front

What decreases the activation energy needed for a chemical reaction?

Back

A catalyst.

Front

What happens to the rate of a biochemical reaction if the activation energy is lowered?

Back

The reaction will happen faster.

Front

What are enzymes an example of?

Back

Proteins.

Front

Define activation energy.

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the role of a catalyst in a chemical reaction?

Back

To lower the activation energy and increase the reaction rate.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.

Front

What is ATP and why is it important?

Back

Adenosine triphosphate (ATP) is the primary energy carrier in cells.

Front

What is the process of converting ADP to ATP called?

Back

Phosphorylation.
