12.6 Photosynthesis

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and Calvin cycle.

Front

Which gas is absorbed by plants during photosynthesis?

Back

Carbon dioxide.

Front

What is the overall equation for photosynthesis?

Back

@@6 ext{CO}_2 + 6 ext{H}_2 ext{O} + ext{light energy} ightarrow ext{C}_6 ext{H}_{12} ext{O}_6 + 6 ext{O}_2@@.

Front

What is the role of light-dependent reactions in photosynthesis?

Back

They convert light energy into chemical energy (ATP and NADPH).

Front

What is the Calvin cycle?

Back

A series of reactions that convert carbon dioxide into glucose using ATP and NADPH.

Front

What is produced during the light-dependent reactions?

Back

ATP, NADPH, and oxygen.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point.

Front

What is the significance of chlorophyll in photosynthesis?

Back

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

Front

What happens to oxygen produced during photosynthesis?

Back

It is released into the atmosphere as a byproduct.

Front

What factors can limit the rate of photosynthesis?

Back

Light intensity, carbon dioxide concentration, and temperature.
