Photosynthesis Review

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

Where do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll, 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-dependent reactions to release oxygen.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP and NADPH, which are used in the Calvin Cycle.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the products of photosynthesis?

Back

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

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 limit the rate.
