Calvin cycle

Name and briefly describe the 3 phrase of the Calvin Cycle

1. Carbon Fixation: CO2 molecules, one at a time by attracting to a 5-carbon sugar 2. Reduction: 3-phosphoglycerate receives an additional phosphate group from ATP 3. Regeneration of CO2: carbon skeleton of 5-molecule of G3P

Fill in the blanks: To synthesize one glucose molecule, the Calvin cycle operates___ times, using___molecules of CO2, ___molecules of ATP, and ___molecules of NADPH

6,6,12,12

ADP+P

ADP+P is used in Photosystem I and Photosystem II and is Produced in The Calvin Cycle

ATP

ATP is produced in Photosystem I and Photosystem II, ATP is used in The Calvin Cycle

What is Rubisco?

An enzyme that catalyzes this first step addition CO2 -> RuBP

The Calvin cycle makes 6 glyceraldehyde-3-phosphates

It turns G3P into sugar

O2 (oxygen)

Oxygen is produced in Photosystem II

NADPH

Produced in Photosystem I, Used in the Calvin Cycle

Which of the following does not occur in the Calvin Cycle?

The release of oxygen does not occur in the Calvin cycle

NADP+

Used in Photosystem I and produced in The Calvin Cycle

H2O (water)

H2O is used in photosystem II

Which of the following sequences correctly represent the flow of electrons during photosynthesis?

H2O to NADPH to The Calvin Cycle

What makes the Calvin cycle a cycle?

Half of the G3P regenerates

CO2 (carbon dioxide)

Carbon Dioxide is used in both Photosystem I and Photosystem II and The Calvin Cycle

Glucose

Glucose is produced in the Calvin Cycle, Glucose is not used in Photosystem I and Photosystem II

What energy transformation takes place in the Calvin Cycle?

The Cycle incorporates carbon from the air and turns it into carbohydrates

Where does the Calvin Cycle take place?

The Stroma

what way does the Calvin cycle depend on the light reactions?

The light reaction provides no sugar, that happens in the second stage of photosynthesis in the Calvin Cycle
