Photosynthesis and Metabolism

Front

What is photosynthesis?

Back

Photosynthesis is the process by which cells synthesize organic compounds from inorganic molecules in the presence of sunlight.

Front

What pigment is primarily involved in photosynthesis?

Back

Chlorophyll is the main pigment involved in photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs within the chloroplasts in plant cells.

Front

What is the role of light in photosynthesis?

Back

Light energy is absorbed by pigments and converted into chemical energy (ATP) during the light-dependent reactions.

Front

What is produced as a by-product of photosynthesis?

Back

Oxygen is produced as a by-product of photosynthesis.

Front

What is chromatography used for in photosynthesis studies?

Back

Chromatography is used to separate and identify photosynthetic pigments.

Front

What is the absorption spectrum?

Back

The absorption spectrum shows the amount of light absorbed by pigments at different wavelengths.

Front

What is the action spectrum?

Back

The action spectrum shows the rate of photosynthesis at each wavelength of light.

Front

What happens during the light-dependent reactions?

Back

Light-dependent reactions convert light energy into chemical energy (ATP) and produce oxygen from water.
