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 main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the stroma?

Back

The stroma is the fluid-filled space surrounding the thylakoids in chloroplasts where the light-independent reactions (Calvin cycle) occur.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH.

Front

What are light-independent reactions?

Back

Light-independent reactions, also known as the Calvin cycle, use ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is an energy carrier that provides the reducing power needed for the conversion of carbon dioxide into glucose during the light-independent reactions.

Front

What is the significance of ATP in photosynthesis?

Back

ATP is an energy molecule that provides the energy required for various biochemical reactions, including the light-independent reactions of photosynthesis.

Front

What is the equation for photosynthesis?

Back

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