In order to produce one molecule of glucose, the Calvin cycle uses _____ molecules of ATP and ______molecules of NADPH.
For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase can be used more than once.
Calvin cycle can be organized into 3 basic stages. During the stage, the enzyme catalyze the fixation of by ribulose biphosphate. For each CO2 and RuBP, two molecules of get formed. During the phase, and are used to convert 6 molecules of 3-PGA into G3P. During the phase, one molecule of G3P leaves the Calvin cycle to contribute to the formation of other compounds needed by the plant. The remaining 5 molecules of G3P regenerate . This enables the system to fix more .

Which of the following is NOT a true difference between the two cycles? Both involve CO2, but in the Calvin cycle CO2 is used brought into the process as a source of carbon for the sugar being built. In the Mitochondrion, CO2 is removed from the sugar and leaves the cell. In the Calvin cycle, ATP is used to carry chemical energy from the light reactions to the the Calvin cycle where the chemical energy is incorporated in the sugar molecule that is being manufactured. In the mitochondrion, ATP is produced and brought out of the mitochondrion so it can provide chemical energy to the many activities going on in the cytoplasm The first step in the Calvin cycle, the carboxylation of RuBP, produces a 12-carbon product that splits into two 6 carbon pieces.

- The high energy molecules that provide the energy to run the reactions of the Calvin cycle are ______________ and ________________. During the first step in the Calvin cycle, a molecule of carbon dioxide gas binds to a 5-carbon molecule called Ribulose 1,5-biphosphate (RuBP). This step of the Calvin cycle is called: ___________________________. After three carbon dioxide molecules have been fixed to three RuBP and the Calvin cycle completes one turn, the organic molecule that is produced is _______________________. Once two of the molecules from the previous blank have been produced, they can combine to make a single six-carbon __________________________ molecule.arrow_forwardWhich of the following statements related to the Calvin Cycle is CORRECT? Six molecules of G3P are produced for every three carbon dioxide that undergo calvin cycle Carbon dioxide is attached to 3-phosphoglycerate resulting is 2 RuBP The regeneration of RuBP is important because it is directly used for the production of starch, cellulose, and glucose. One molecule of G3P exits the calvin cycle and five is used to form glucose for the production of starch, cellulose, and sucrose.arrow_forwardWhat is the name of the molecule that transports high energy electrons from the light reactions to the Calvin Cycle?
