There are some similarities and some differences between the citric acid cycle in the mitochondrion and the Calvin cycle in photosynthesis.  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.  In the first step of the citric acid cycle, the first molecule produced contains 6 atoms.  In the citric acid cycle in the mitochondrion, the product of the first step, citric acid, contains 3 carbons.     In the Calvin cycle, high energy electrons are added to the organic molecules being synthesized.  In the citric acid cycle, high energy electrons are stripped off the organic molecules that come into the cycle.
