AP Photosynthesis Review

Front

What colors of light does chlorophyll absorb strongly?

Back

Chlorophyll absorbs strongly in the red and blue parts of the visible spectrum.

Front

What is the relationship between the light reactions and the Calvin cycle?

Back

The light reactions provide ATP and NADPH to the Calvin cycle, and the Calvin cycle returns ADP, ℗i, and NADP+ to the light reactions.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

Front

How do C4 plants differ from C3 plants in terms of CO2 fixation?

Back

C4 plants can continue to fix CO2 even at relatively low CO2 concentrations and high oxygen concentrations.

Front

Where do the enzymatic reactions of the Calvin cycle occur?

Back

The enzymatic reactions of the Calvin cycle occur in the stroma of the chloroplast.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

The primary function of chlorophyll in photosynthesis is to absorb light energy, which is then used to convert carbon dioxide and water into glucose and oxygen.

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 produced during the light reactions of photosynthesis?

Back

The light reactions produce ATP, NADPH, and oxygen.

Front

What role does rubisco play in the Calvin cycle?

Back

Rubisco is the enzyme that catalyzes the first step of the Calvin cycle, fixing carbon dioxide to ribulose bisphosphate (RuBP).

Front

What is photorespiration and why is it a problem for plants?

Back

Photorespiration is a process where rubisco fixes oxygen instead of carbon dioxide, leading to a loss of energy and carbon for the plant.
