Photosynthesis

Front

What is photosynthesis?

Back

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

What is the ultimate ORIGINAL source of energy for living things?

Back

Sun

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 of photosynthesis occur?

Back

Thylakoid membranes of the chloroplasts.

Front

Where do the light-independent reactions of photosynthesis occur?

Back

Stroma of the chloroplasts.

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 is essential for photosynthesis.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during the light-dependent reactions and used in the light-independent reactions to synthesize glucose.

Front

What enzyme facilitates chemiosmosis in photosynthesis?

Back

ATP Synthase.

Front

What is the significance of the Calvin cycle?

Back

The Calvin cycle is the light-independent reaction that converts carbon dioxide and other compounds into glucose, using ATP and NADPH produced in the light-dependent reactions.

Front

What is the equation for photosynthesis?

Back

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