Photosynthesis and the Calvin Cycle

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, 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 the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

How many G3P molecules are needed to form one molecule of glucose?

Back

2 G3P molecules are needed to form one molecule of glucose.

Front

What is the final electron acceptor in the light-dependent reactions of photosynthesis?

Back

NADPH is the final electron acceptor in the light-dependent reactions.

Front

What is the primary advantage of using cycles in biological production processes?

Back

They reduce the amount of energy required.

Front

How many carbons are in a molecule of glucose?

Back

A molecule of glucose contains 6 carbons.

Front

What is the primary source of energy for plants?

Back

The primary source of energy for plants is sunlight.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is an energy-carrying molecule that provides energy for various cellular processes, including the Calvin Cycle in photosynthesis.
