ATP and Photosynthesis

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment that absorbs light energy for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages 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 produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to convert carbon dioxide and water into glucose and oxygen.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide and water.
