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

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membranes of chloroplasts.

Front

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

Back

The main purpose of the light-dependent reactions is to capture energy from sunlight and convert it into chemical energy in the form of ATP and NADPH.

Front

What is the overall equation for photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, and plays a crucial role in converting light energy into chemical energy.

Front

What are the products of the light-dependent reactions?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of starch in plants?

Back

Starch is a polysaccharide that serves as a storage form of energy in plants, synthesized during photosynthesis.

Front

What are the main components required for photosynthesis?

Back

The main components required for photosynthesis are sunlight, carbon dioxide, and water.

Front

What is the function of the thylakoid membrane?

Back

The thylakoid membrane contains chlorophyll and is the site of the light-dependent reactions of photosynthesis.
