He has access to the following inhibitors: Rotenone-an electron transport chain inhibitor, Oligomycinan-an ATP synthase inhibitor, and TLN232-an inhibitor of glycolysis. Which inhibitor should he use to slow down initial substrate-level phosphorylation that occurs once glucose has crossed the plasma membrane?
A. TLN-232
B. oligomycin
C. rotenone
