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

Front

What factors affect the rate of photosynthesis?

Back

CO2 concentration, H2O availability, Temperature, Light intensity - All of the above

Front

How does a competitive inhibitor affect an enzyme's function?

Back

It binds to the active site, preventing the enzyme from catalyzing the reaction.

Front

What are the products of the Krebs Cycle?

Back

NADH, FADH2, carbon dioxide, ATP

Front

Why do plants not store 100% of the light energy absorbed by chlorophyll in glucose molecules?

Back

Most of the energy is used to power the reaction or is lost as heat.

Front

Define photosynthesis.

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, to drive the photosynthetic process.

Front

Explain the difference between aerobic and anaerobic respiration.

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the function of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

What is the significance of the electron transport chain in cellular respiration?

Back

The electron transport chain generates ATP through oxidative phosphorylation by transferring electrons and pumping protons across the membrane.
