Answer:
The correct answer is NADPH.
Explanation:
It takes 6 molecules of CO2 to generate one molecule of glucose. Each of the CO2 molecules is attached to a RuBP-acceptor molecule, which is then divided into two 3-phosphoglycerate molecules.
The ATP produced during the light reactions of photosynthesis yields phosphate groups to these molecules, resulting in 1,3-diphosphoglycerate. Simultaneously, NADPH yields electrons to these three-carbon molecules, creating glyceraldehyde-3-phosphate molecules. Glyceraldehyde-3-phosphate is used to make the sugar from 6 glucose carbons. Another part of the glyceraldehyde-3-phosphate is used together with an ATP molecule, to generate the CO2 acceptor ribulose-1,5-bisphosphate and start the cycle again.
Have a nice day!
