Since you have posted multiple questions, we will provide the solution only to the first question as per our Q&A guidelines. Please repost the remaining questions separately.Calvin-Benson-Bassham cycle is commonly known as the Calvin cycle or Dark reactions of photosynthesis, not because it occurs in dark but because it does not require light i.e. it is light independent. The Calvin cycle starts with atmospheric carbon dioxide (CO2) passing through the stomata into the intercellular spaces → CO2 enters mesophyll cells → diffuses into the stroma of the chloroplast. Stroma is the site of the Calvin cycle. The different phases of the Calvin cycle are described below. The assimilation of carbon dioxide to produce 3-PG occurs in the phase 1 of Calvin cycle. 3 molecules of 5-carbon ribulose 1,5-bisphosphate (RuBP) combine with 3 molecules of CO2 to make 6 molecules of 3-carbon 3-phosphoglycerate (3-PG). The reaction is catalysed by ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) enzyme.3 CO2 + 3 RuBP −−RuBisCO−→ 6 3-PGFormation of GA3P from 3-PG occurs in phase 2 of the Calvin cycleThese 6 molecules of 3-PG are then phosphorylated to 6 molecules of 1,3 bisphosphoglycerate at the expense of 6 ATP. 1,3 bisphosphoglycerate is then reduced to 6 molecules of glyceraldehyde 3-phosphate (GA3P) at the expense of 6 NADPH by glyceraldehyde 3-phosphate dehydrogenase. 6 3-PG + 6 ATP + 6 NADPH −−Glyceraldehyde 3−phosphate dehydrogenase−→ 6 GA3P + 6 ADP + 1 NADPRegeneration of ribulose 1,5-bisphosphate from GA3P occurs in phase 3 of the Calvin cycle. Out of 6 glyceraldehyde 3-phosphate, only 1 enters the pathway that produces glucose in the end while 5 are converted to 3 molecules of ribulose 5-phosphate which is then phosphorylated at the expense of 3 ATP to regenerate ribulose 1,5-bisphosphate by ribulose-5-phosphate kinase. The cycle uses 3 RuBP to generate 6 GA3P through phase 1 and 2.1 GA3P is 'lost' for glucose synthesis and 5 is used for regenerating RuBP in phase 3. Since RuBP is both the precursor and end product of the series of enzyme catalysed reaction, it forms a closed-loop or cyclic pathway. So Calvin's cycle is a 'cycle'. In chloroplast, water is split in Photosystem II, releasing electrons that are used for generating a proton gradient for ATP synthesis. The electrons then move to Photosystem I, where they are used to reduce NADP+ to NADPH.In Calvin cycle phase 2, ATP and NADPH are used for reducing 3-PG to GA3P. So in Calvin cycle, only ATP and NADPH are the molecules that have energy derived from light. To summarise, phase 1 catalyses the assimilation of carbon dioxide. RuBisCO catalyses this assimilation. phase 3 described the regeneration of RuBP from GA3P via the catalytic activity of ribulose-5-phosphate kinase. RuBP is both the precursor and end product of dark reactions of photosynthesis, hence, a cycle. in Calvin's cycle, ATP and NADPH are the molecules that have energy derived from light.
