Answer :
Final answer:
The correct options are A) Production of glucose, and C) Regeneration of RuBP. G3P from the Calvin cycle is directly used in the production of carbohydrates like glucose and the regeneration of RuBP, but not in ATP production.
Explanation:
The correct options are A) Production of glucose, and C) Regeneration of RuBP. The glyceraldehyde-3-phosphate (G3P) produced at the end of the second phase of the Calvin cycle is directly used for multiple purposes within the photosynthetic process of plants. Firstly, G3P is involved in the production of carbohydrate molecules, including glucose. Additionally, G3P is crucial in the regeneration of Ribulose-1,5-bisphosphate (RuBP), a molecule that is necessary to continue the carbon fixation process of the Calvin cycle. While G3P is not directly used for the production of ATP, it is a product of the reactions that use ATP and NADPH to reduce CO2.
