Unit 3 AP Biology Insta-Review (Cellular Energetics)

Front

How many carbon dioxides are used in the Calvin Cycle?

Back

3

Front

What molecule is responsible for powering cellular processes?

Back

ATP

Front

What happens to an enzyme if the temperature increases too high?

Back

Enzyme denatures

Front

If the concentration of hydrogen ions increases, what happens to pH?

Back

pH decreases

Front

What type of reaction is characterized by the absorption of energy?

Back

Endergonic

Front

What is the primary function of ATP in cells?

Back

To provide energy for cellular processes.

Front

What is the role of enzymes in biochemical reactions?

Back

To speed up reactions by lowering activation energy.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity increases with temperature up to a certain point, then decreases due to denaturation.

Front

What is the relationship between pH and enzyme activity?

Back

Each enzyme has an optimal pH range for activity; deviations can reduce activity.

Front

What is the difference between endergonic and exergonic reactions?

Back

Endergonic reactions absorb energy, while exergonic reactions release energy.
