AP Biology Unit 3: Cellular Energetics Review

Front

What are the products of the light reaction needed by the Calvin cycle in photosynthesis?

Back

ATP and NADPH are the products of the light reaction that are directly needed by the Calvin cycle.

Front

What is a control in scientific experiments?

Back

A control is a test that does not have the independent variable, used to show a baseline with no reaction.

Front

What powers the rotation of ATP synthase enzymes in mitochondria and chloroplasts?

Back

The diffusion of hydrogen ions powers the rotation of ATP synthase enzymes.

Front

When does lactic acid build up in animal cells?

Back

Lactic acid builds up when there is not enough oxygen to fuel the mitochondria.

Front

What process creates the proton motive force in cellular respiration?

Back

The electron transport chain creates the proton motive force in cellular respiration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is the function of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various biochemical reactions.
