AP Biology - Cellular Respiration+Photosynthesis

Front

What happens to the oxygen levels if a plant is left in the dark overnight?

Back

Oxygen levels go down due to cellular respiration.

Front

What does a C4 plant do?

Back

A C4 plant stores CO2 in a separate cell from its photosynthetic cell during the day.

Front

What is NADP+ in the context of photosynthesis?

Back

NADP+ is reduced during the light reaction.

Front

What substances from the light reaction are required for the Calvin cycle?

Back

The Calvin cycle requires ATP and NADPH from the light reaction.

Front

Is photosynthesis an energy-storing process?

Back

Yes, photosynthesis is an energy-storing process (in glucose) while cellular respiration is an energy-releasing process (to ATP).

Front

What is the primary function of photosynthesis?

Back

The primary function of photosynthesis is to convert light energy into chemical energy stored in glucose.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

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

What is the equation for cellular respiration?

Back

The equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is the difference between aerobic and anaerobic respiration?

Back

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