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 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 and NADPH.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions of photosynthesis.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the light-independent reactions, is the process in which carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of water in photosynthesis?

Back

Water is essential in photosynthesis as it provides electrons and protons for the light-dependent reactions and is split to release oxygen as a byproduct.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the role of NADPH in photosynthesis?

Back

NADPH is an electron carrier that provides the reducing power needed for the Calvin Cycle to convert carbon dioxide into glucose.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may become limiting.
