QUESTION 5 The citric acid cycle must operate continuously to provide electrons for ATP generation. It is also a sensor of metabolic status and is able to fine tune metabolic flux through coordinated allosteric regulation of key enzymes in the pathway. Indicate the effect of the change in the following metabolite concentrations on the overall flux of the pathway. Change in metabolic status change in metabolic flux through citric acid cycle increased energy...
