SP26 E2 Q23 Which glycolytic intermediate is directly shared with the pentose phosphate pathway and determines whether glucose flux enters glycolysis or the PPP?

SP26 E2 Q49 During a transition from rest to vigorous muscle activity, mitochondrial ATP levels fall, ADP and NAD⁺ rise, and intracellular Ca²⁺ increases. Which combination of regulatory effects on the TCA cycle most accurately reflects how flux through the cycle changes under these conditions?
