PHOTOSYNTHESIS

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of the light reactions of photosynthesis?

Back

The main products of the light reactions are ATP, NADPH, and oxygen.

Front

Which pigment is primarily responsible for photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that performs photosynthesis.

Front

What is the role of ATP in photosynthesis?

Back

ATP provides the energy required for the synthesis of glucose during the Calvin cycle.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to convert carbon dioxide into glucose.

Front

What are grana in chloroplasts?

Back

Grana are stacks of thylakoids in chloroplasts where the light reactions of photosynthesis take place.

Front

What is the function of stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

How does temperature affect photosynthesis?

Back

High temperatures can slow photosynthesis because they can denature enzymes involved in the process.

Front

What color of light is least absorbed by chlorophyll?

Back

Green light is least absorbed by chlorophyll; it is reflected, which is why plants appear green.

Front

What is the overall equation for photosynthesis?

Back

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