- A new ATP-producing protein is discovered that couples ATP production to the oxidation of NADPH by oxidative phosphorylation. Assume that the value of ΔGo for ATP synthesis is 30 kJ•mol−1. If this protein only produces 1 molecule of ATP per reaction that consumes one NADPH: a. How much free energy is wasted, under standard conditions?b. How many more ATP molecules could be created by a perfectly efficient electron transport chain from one NADPH?Assuming all the NADH+H+ and FADH2 are used for oxidative phosphorylation, how many net ATP are made from 1 molecule of glucose? (hint: don’t forget to also include substrate level phosphorylation)A substantial amount of energy is put into the photosynthetic electron transport to extract electronsf from water and to elevate the energy level of ferredoxin to a very strong reductant. The amount of energy in one NADPH is 218 kJ.mol-1. What is the percentage of this energy conserved in NADPH for the production of one mole of oxygen? What happened to the rest of the energy?

Ubiquinol (QH2) is also the entry point for electrons from NADH of flavoproteins.i. Cytochrome reductase catalyzes the transfer of electrons from cytochrome c to O2.If decanoic acid (10 : 0) undergoes complete β-oxidation in mitochondria, how many net ATP is yielded? (NADH = 2.5 ATP; FADH2 = 1.5 ATP; Acetyl CoA = 10 ATP) Answer in number onlyA group of researchers are interested in producing hydrogen gas from microbial cells. They want to know the maximum theoretical yield of H2 per molecule of glucose.
