ln Lecture 8, page 12, 3rd line, you said, "Glu ---> ...". What did you mean by coupling formation of ATP? I thought coupling usually refers to making ADP in an exergonic rxn.
I cannot find this reference, as the page number depends on your printer. But, no, coupling refers to two otherwise independent reactions that are obligatorily carried out together by the enzyme. Thus when ATP is produced by substrate-level phosphorylation, it is via coupled reactions producing ATP from ADP + Pi, as in the 2 relevant steps (7 and 10) in glycolysis. These are coupled reactions just like hexokinase (think of the hexokinase reaction in reverse, still coupled).
