What is the Calvin Cycle?

Back

The Calvin Cycle is a series of light-independent reactions in photosynthesis where energy from ATP and NADPH is used to convert carbon dioxide into glucose.

Front

What is the role of Rubisco in photosynthesis?

Back

Rubisco is the enzyme that catalyzes the fixation of carbon dioxide in the Calvin Cycle, making it essential for the synthesis of organic compounds.

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle occurs in the stroma of chloroplasts.

Front

What are the main products of the Calvin Cycle?

Back

The main products of the Calvin Cycle are glucose, ADP, and NADP+.

Front

What is the function of electron transport chains in photosynthesis?

Back

Electron transport chains are series of proteins that shuttle high-energy electrons during ATP-generating reactions, crucial for the light-dependent reactions.

Front

What is the stroma in the context of chloroplasts?

Back

The stroma is the fluid portion of the chloroplast, located outside of the thylakoids, where the Calvin Cycle takes place.

Front

What are light-independent reactions?

Back

Light-independent reactions, also known as the Calvin Cycle, do not require light directly and use ATP and NADPH produced in light-dependent reactions to synthesize glucose.

Front

What is the significance of NADPH in the Calvin Cycle?

Back

NADPH provides the reducing power needed to convert 3-phosphoglycerate into glyceraldehyde-3-phosphate, a precursor to glucose.

Front

How does ATP contribute to the Calvin Cycle?

Back

ATP provides the energy required for the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate during the Calvin Cycle.

Front

What is the relationship between the light-dependent and light-independent reactions?

Back

The light-dependent reactions capture energy from sunlight to produce ATP and NADPH, which are then used in the light-independent reactions (Calvin Cycle) to synthesize glucose.
