WebThe reverse reaction is catalyzed by fructose-2,6-bisphosphatase (FBPase-2) and is also subject to regulation. In general terms, anything that will suppress glycolysis and activate gluconeogenesis will activate FBPase-2. For example, increased glucagon is released when blood glucose concentrations are low. In this state, glycolysis will not ... Gluconeogenesis is a pathway consisting of a series of eleven enzyme-catalyzed reactions. The pathway will begin in either the liver or kidney, in the mitochondria or cytoplasm of those cells, this being dependent on the substrate being used. Many of the reactions are the reverse of steps found in glycolysis. • Gluconeogenesis begins in the mitochondria with the formation of oxaloacetate by the carboxyl…
