- The Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation?

ATP production would increase since glycolysis would be using less ATP. The Krebs cycle production of FADH2 would increase. O The Krebs cycle would continue to function at a normal rate. O The Krebs cycle production of NADH would decrease.Give all the reactions that will produce ATP either by substrate-level phosphorylation (SLP) or by oxidative phosphorylation (OP).

ATP in Glucose Prep. phase Payoff phase ļ - MacRoc Pyruvate →→→ Anaerobic fate of pyruvate ATP out ▬OD OF 1- HP 01 -- Select one: O a. No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD+ to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis.
