Question

During the Calvin cycle, the metabolic pathway in which coz is faced during photosynthesis, dihydroxyacetone phosphate (DHAP) and erythrose 4-phosphate (E4P) are combined to form sedoheptulose-1,7-bisphosphate (SBP): DHAP E4P SBP CHOPO C=0 + H-C-OH H-C-OH CHOPOS CHOPOS H-C=0 c=0 HO-C-H CH,OH H-C-OH нес-он H-C-OH CHOPO Question 5a (1 pt): This reaction resembles the reverse of one reaction in glycolysis. Which reaction is it and what is the enzyme that catalyzes it? Question 5b (1 pt): In the space below, write out a reasonable mechanism (using either covalent or 2n metal-on catalysis) for this reaction.

Answer 1

The mechanism for the given transformation can be written as follows.
