Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts in photosynthetic organisms, where carbon dioxide is fixed and converted into glucose using ATP and NADPH.

Front

What are the main reactants of the Calvin Cycle?

Back

The main reactants of the Calvin Cycle are carbon dioxide (CO2), ATP, and NADPH.

Front

What is RuBP and its role in the Calvin Cycle?

Back

RuBP (Ribulose bisphosphate) is a 5-carbon sugar that combines with CO2 in the Calvin Cycle to initiate the process of carbon fixation.

Front

What is G3P and its significance in the Calvin Cycle?

Back

G3P (Glyceraldehyde 3-phosphate) is a 3-carbon sugar produced in the Calvin Cycle, which can be used to form glucose and other carbohydrates.

Front

What is the primary product of the Calvin Cycle?

Back

The primary product of the Calvin Cycle is G3P (Glyceraldehyde 3-phosphate).

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place 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 in the Calvin Cycle.

Front

What is the role of NADPH in the Calvin Cycle?

Back

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

Front

What is the significance of carbon fixation in the Calvin Cycle?

Back

Carbon fixation is the process of converting inorganic carbon (CO2) into organic compounds, which is essential for the synthesis of glucose and other carbohydrates.

Front

What is the function of Rubisco in the Calvin Cycle?

Back

Rubisco (Ribulose bisphosphate carboxylase/oxygenase) is the enzyme that catalyzes the first step of carbon fixation by combining CO2 with RuBP.
