(a) What are the three stages of the Calvin cycle? (b) In stage one, COz is added to an acceptor molecule, which then split into two molecules. What is the acceptor molecule? What is the product? (c) In stage two, the product of stage one is converted in two steps into something else. What is the product? (d) In stage three, five 3-carbon molecules are combined to form three 5-carbon molecules in a series of reactions. What is the enzyme that moves 2-carbon units from one molecule to another? What is the enzyme that moves 3-carbon units? What is the final 5-carbon molecule? (e) Rubisco can also add Oz to the acceptor molecule in stage one. Why is this a wasteful reaction?
