Detailed explanation-1: -Quesdon 9 (2 points) How many carbon dioxide molecules must be added to 6 molecules RuBP t0 make # single molecule of glucose? single molecule of glucose, nine carbon dioxide molecules must be added.
Detailed explanation-2: -How many carbon dioxide molecules must be added to RuBP to make a single molecule of glucose? Six carbon dioxide molecules are required to produce two G3P molecules, which can be combined to make one glucose molecule.
Detailed explanation-3: -It takes a total of six molecules of carbon dioxide to form one molecule of glucose. Since glucose is a six-carbon molecule, it would require six carbon atoms, one from each carbon dioxide molecule.
Detailed explanation-4: -But each turn makes two G3Ps, thus three turns make six G3Ps. One is exported while the remaining five G3P molecules remain in the cycle and are used to regenerate RuBP, which enables the system to prepare for more CO2 to be fixed. Three more molecules of ATP are used in these regeneration reactions.
Detailed explanation-5: -One ATP is used in the regeneration of RuBP.
