cooperation of the light reactions and the Calvin cycle.

The Calvin cycle then reduces the fixed carbon to carbohydrate by the addition of electrons.

Photosynthesis and Calvin Cycle Flashcards | Quizlet

In the photosynthesis takes place in a chloroplast of a thin-walled mesophyll cell and a 4-carbon acid is handed off to a thick-walled bundle sheath cell where the Calvin cycle occurs in a chloroplast of that second cell. This protects the Calvin cycle from the effects of .

To convert C02 to carbohydrate, the Calvin cycle also requires chemical engery in the form of ATP, which is also generated by the light reactions.

Simple steps of the Calvin Cycle? | Yahoo Answers

In the photosynthesis and initial carbon fixation occur at night and a 4-carbon acid is stored in the cell's vacuole. During the day, the Calvin cycle operates in the same chloroplasts.

Thus, it is the Calvin cycle that makes sugar, but it can do so only with the help of the NADPH and ATP produced by the fight reactions.

The cycle is completed when the leftover GP molecules are met with a carbon acceptor and converted into RuBP, which is then joined with carbon dioxide to re-start the cycle." title="Carbon fixation stage in photosynthesis"> It is a result of an enzyme controlled sequence of reactions requiring ATP and hydrogen (NADPH2) from the light stage, and carbon dioxide.

cycle [dark reactions of photosynthesis])?

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

commonly known as Light dependent Reactions and the Calvin Cycle.

Thylakoid membranes, especially those of the grana, are the sites of the light reactions, whereas the Calvin cycle occurs in the stoma.
