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 is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, responsible for absorbing light energy.

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 do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the main product of the light-dependent reactions?

Back

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

Front

What is the role of ATP in photosynthesis?

Back

ATP provides the energy needed for the light-independent reactions (Calvin cycle) to synthesize glucose.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH acts as a high-energy electron carrier that provides reducing power for the light-independent reactions.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6 H2O + 6 CO2 + light energy → 6 O2 + C6H12O6.

Front

What color of light does chlorophyll absorb most effectively?

Back

Chlorophyll absorbs light most effectively in the blue and red wavelengths, while reflecting green light.

Front

What is the significance of the oxygen produced in photosynthesis?

Back

The oxygen produced in photosynthesis is released into the atmosphere and is essential for the respiration of most living organisms.
