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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during photosynthesis to provide energy for various cellular processes.

Front

What is NADPH and its function in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a carrier molecule that transports electrons to the Calvin cycle during photosynthesis.

Front

What is the light-dependent reaction?

Back

The light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where light energy is converted into ATP and NADPH.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that occur in the stroma of chloroplasts, using ATP and NADPH to convert carbon dioxide into glucose.

Front

What is the overall equation for photosynthesis?

Back

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

Front

What is chemiosmosis?

Back

Chemiosmosis is the process by which ATP is produced in the chloroplasts and mitochondria, using a proton gradient across a membrane.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
