Explain, using a simple diagram, the relationship between acyclic photophosphorylation (photophase) and the Calvin cycle (dark phase).
Explain in detail of the stages of photosynthesis without explaining all the reactions of each pathways, but state the key steps of each pathway. Mention the location where each pathway happens in the plant and lastly make a table of the products formed at the end of the stage (ATPs, NADPHs, and water). Discuss about the oxidation-reduction of various molecules that are a part of these pathways.
Explain how CO2 is "fixed" by the Calvin cycle and converted into glyceraldehyde 3-phosphate. (i.e. explain how the whole Calvin cycle works)
Explain briefly why the following ideas are false. a. Photosynthesis is the food-making process done by plants. b The Calvin cycle was called the dark reactions because it can only take place in the absence of light. c. Photosynthesis can only be powered by sunlight.
If an enzyme in the Calvin cycle were knocked out, then a the light-dependent reactions would increase. b the light-dependent reactions would stop. c the light-dependent reactions would diminish. d the light-dependent reactions would be unaffected.
