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 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

What is produced during the light-dependent reactions?

Back

ATP and NADPH are produced during the light-dependent reactions.

Front

What is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

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 process of photosynthesis.

Front

What is the significance of ATP in photosynthesis?

Back

ATP provides the energy needed for various biochemical reactions during the light-independent reactions (Calvin cycle) of photosynthesis.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH acts as a reducing agent, providing the electrons needed for the conversion of carbon dioxide into glucose during the Calvin cycle.

Front

What is a limiting factor in photosynthesis?

Back

A limiting factor is any condition that restricts the rate of photosynthesis, such as light intensity, carbon dioxide concentration, or temperature.
