Photosynthesis

Front

What is the role of NADP+ in photosynthesis?

Back

NADP+ is reduced during the light reaction, acting as an electron carrier.

Front

What is a granum?

Back

A granum is a stack of thylakoids found in chloroplasts.

Front

Where does the Calvin cycle occur?

Back

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

Front

Which factor has the least effect on the rate of photosynthesis?

Back

Increasing the amount of O2 from 20% to 30% in the air has the least effect.

Front

Where does the carbon used to form glucose come from?

Back

The carbon comes from CO2 in the air.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light reactions of photosynthesis occur.

Front

What is the primary function of chlorophyll?

Back

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

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the significance of the light-dependent reactions?

Back

They convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the function of the stroma in chloroplasts?

Back

The stroma is the fluid-filled space where the Calvin cycle occurs.
