Question
Assume that the substrate cycle that exists as shown undergoes reciprocal regulation such that the production of B is
upregulated by 50% and the production of A is downregulated by 50%. What will the next flux of B in this situation be?
ATP

105
What would be the net flux of B if the kinase activity was
downregulated by 50% and the phosphatase activity
upregulated by 50%, starting from the initial conditions described?
