The Calvin Cycle

Front

What is the primary function of the Calvin Cycle in green plants?

Back

To construct simple sugars from carbon dioxide.

Front

What are the main inputs used in the Calvin Cycle?

Back

Carbon dioxide and energy (ATP and NADPH) are used to make organic compounds.

Front

What does carbon combine with to form glucose in the Calvin Cycle?

Back

RuBP (Ribulose bisphosphate).

Front

Which molecule is not directly needed for the Calvin Cycle?

Back

H2O (Water).

Front

What is the unstable six-carbon sugar produced in the Calvin Cycle?

Back

It breaks into two molecules of 3-PGA (3-phosphoglycerate).

Front

Where does the Calvin Cycle occur in plant cells?

Back

In the stroma of chloroplasts.

Front

What is the role of ATP in the Calvin Cycle?

Back

ATP provides the energy required for the conversion of 3-PGA to G3P.

Front

What is the role of NADPH in the Calvin Cycle?

Back

NADPH provides the reducing power (electrons) needed to convert 3-PGA to G3P.

Front

What is G3P and its significance in the Calvin Cycle?

Back

G3P (Glyceraldehyde-3-phosphate) is a three-carbon sugar that can be used to form glucose and other carbohydrates.

Front

How many turns of the Calvin Cycle are needed to produce one molecule of glucose?

Back

Six turns of the Calvin Cycle are needed to produce one molecule of glucose.
