Photosynthesis - Overview

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 reactions and the Calvin cycle (light-independent reactions).

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split during the light reactions to release oxygen.

Front

What is the main product of the Calvin cycle?

Back

The main product of the Calvin cycle is G3P (glyceraldehyde-3-phosphate), which can be used to form glucose.

Front

How many ATP and NADPH are produced in the light reactions?

Back

The light reactions produce ATP and NADPH, which are used in the Calvin cycle.

Front

What is the function of the thylakoid membrane?

Back

The thylakoid membrane is where the light reactions of photosynthesis take place, housing the photosystems and electron transport chain.

Front

What is the significance of the Calvin cycle?

Back

The Calvin cycle is significant because it converts carbon dioxide into organic compounds, such as glucose, using ATP and NADPH from the light reactions.

Front

What is the equation for photosynthesis?

Back

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