Photosynthesis Practice

Front

What are the two products of the light reactions that are needed for the Calvin cycle?

Back

NADPH and ATP

Front

What is the principal chemical compound that living things use to store energy?

Back

ATP

Front

TRUE or FALSE: When the concentration of carbon dioxide decreases, the rate of photosynthesis also decreases.

Back

TRUE

Front

What happens to carbon dioxide levels in a sealed ecosystem at night?

Back

Carbon increases at night because there is less photosynthesis and more cellular respiration occurring in the plant.

Front

What is the primary function of the Calvin cycle in green plants?

Back

Construct sugar from carbon dioxide.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for the photosynthesis process.

Front

What are the main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is the formula for photosynthesis?

Back

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

Front

What is the significance of ATP in photosynthesis?

Back

ATP provides the energy required for the Calvin cycle to synthesize glucose.
