AP_ Unit 3_ Enz & Energy_ CALVIN CYCLE

Front

What are the three phases of the Calvin Cycle?

Back

1. Carbon Fixation 2. Reduction 3. Regeneration of RuBP

Front

What is the main product of the Calvin Cycle?

Back

Glucose

Front

What is RuBP in the context of the Calvin Cycle?

Back

RuBP (Ribulose bisphosphate) is a 5-carbon sugar that combines with CO2 during the Calvin Cycle.

Front

How does high temperature affect photosynthesis?

Back

High temperatures can denature enzymes, slowing down the rate of photosynthesis.

Front

What role do ATP and NADPH play in the Calvin Cycle?

Back

ATP and NADPH provide the energy and reducing power needed to convert carbon dioxide into organic compounds.

Front

Where does the Calvin Cycle occur in the plant cell?

Back

The Calvin Cycle occurs in the stroma of chloroplasts.

Front

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

Back

Carbon fixation is the process of converting inorganic CO2 into organic compounds, which is essential for building carbohydrates.

Front

What is the function of the enzyme RuBisCO in the Calvin Cycle?

Back

RuBisCO catalyzes the reaction between CO2 and RuBP, initiating the process of carbon fixation.

Front

What is 3-PGA and its role in the Calvin Cycle?

Back

3-PGA (3-phosphoglycerate) is a 3-carbon compound formed after the fixation of CO2 and is a key intermediate in the Calvin Cycle.

Front

What happens during the reduction phase of the Calvin Cycle?

Back

In the reduction phase, ATP and NADPH are used to convert 3-PGA into G3P (glyceraldehyde-3-phosphate), a 3-carbon sugar.
