Detailed explanation-1: -Rubisco catalysis the connection of the small molecule ribulose-1.5-bisphosphate phosphate (RuBP) to carbon dioxide-therefore fixing the inorganic CO2 as an organic molecule. RuBP contains 5 carbons as well as oxygen, hydrogen and phosphate and it bonds to the CO2 to create a 6 carbon molecule.
Detailed explanation-2: -Six “turns” of the Calvin cycle use chemical energy from ATP to combine six carbon atoms from six CO2 molecules with 12 “hot hydrogens” from NADPH. The result is one molecule of glucose, C6H12O6.
Detailed explanation-3: -It would take six turns of the cycle, or 6 CO2start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH, to produce one molecule of glucose.
Detailed explanation-4: -Carbon dioxide molecules enter the Calvin cycle from the atmosphere. Energy from ATP and high-energy electrons from NADPH are used to convert 3-carbon molecules into similar (ALTERED) 3-carbon molecules. The Calvin cycle uses six molecules of carbon dioxide to produce a single 6-carbon sugar molecule.
Detailed explanation-5: -A molecule of glucose is made up of six carbon molecules. Therefore, six turns will be required for the synthesis of one molecule of glucose by Calvin cycle.
