- The metabolic reactions and enzymes that require NAD/NADH are shown in Figure 1. However, it is not specified whether oxidized or reduced NAD is used in each reaction, nor what form of NAD is produced as a product. Add this specificity to the attached figure. You are also welcome to draw your own figure.Some anaerobic prokaryotes use nitrate (NO3- ) as the terminal electronacceptor for energy metabolism. Assuming 100% effi ciency, how much ATP could be synthesized by the oxidation of NADH by nitrate?Give all the reactions that will produce ATP either by substrate-level phosphorylation (SLP) or by oxidative phosphorylation (OP).

In glycolysis, two key reactions to produce ATP occur because an unfavorable reaction is coupled to another reaction that is thermodynamically favorable. The reaction catalyzed by citrate synthase, shown on the right, is similarly coupled to an unfavorable reac- tion in the TCA cycle. Write the unfavorable reaction using structural formulas and write the key step that drives the two coupled reactions forward. What is the overall AG'o of the coupled reactions?

To capture and use the energy in glucose to make ATP, we must utilize 4 different sequential pathways/steps. Starting with one glucose molecule and eventually ending with CO, H;O and ATP, list the 4 pathways/steps in order and tell me what molecules enter each pathway, and what the final products of each pathway are.
