Calvin Cycle

Front

What is RuBP?

Back

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

Front

True or False: The Calvin Cycle returns ADP and NADP+ to the light dependent phase.

Back

True

Front

Why do plants close their stomata when the temperature is hot?

Back

To prevent water loss.

Front

What is the ultimate ORIGINAL source of energy for living things?

Back

The Sun.

Front

What happens to the remaining G3P molecules in the last step of the Calvin Cycle?

Back

They are shuffled to regenerate RuBP by adding ATP.

Front

What are the three main phases of the Calvin Cycle?

Back

Carbon fixation, Reduction phase, Regeneration of RuBP.

Front

What role does ATP play in the Calvin Cycle?

Back

ATP provides energy for the conversion of 3-PGA to G3P and for regenerating RuBP.

Front

What is the function of NADPH in the Calvin Cycle?

Back

NADPH provides reducing power to convert 3-PGA into G3P.

Front

What is the primary product of the Calvin Cycle?

Back

G3P (Glyceraldehyde-3-phosphate), which can be used to form glucose.

Front

How many molecules of CO2 are required to produce one G3P molecule?

Back

Three molecules of CO2 are required to produce one G3P molecule.
