For the theoretical maximum yield of ATP per glucose molecule oxidized by aerobic respiration, we will assume that for each pair of electrons transferred to the electron transport chain by NADH, 3 ATP will be generated; for each electron pair transferred by FADH2, 2 ATP will be generated. If NADH is produced in the cytoplasm, it will only generate 2 ATP but NADH produced in the mitochondria will release 3 ATP. In a complete breakdown of a molecule of glucose, how many molecules of NADH had been produced?

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?
In the presence of excess oxygen, a complete oxidation of seven molecules of glucose into carbon dioxide and water, by a yeast cell, would produce approximately ATP molecules via oxidative phosphorylation only. (Consider NADH = 3 ATP and FADH2 = 2 ATP)
A poison that prevents the transfer of electrons from the last [Fe-S] cluster of Complex I to coenzyme Q is added to a suspension of actively respiring mitochondria. Which of the following will be observed? ATP production would be impaired due to the uncoupling of oxidative phosphorylation from electron transport. ATP production would be reduced due to inhibition of the CoQ subunit of ATP synthase. ATP production would be reduced due to a decrease in the number of protons pumped out of the mitochondrial matrix. ATP production would be halted completely due to the block in electron transport through the electron transport chain.
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)
During cellular respiration, for each single glucose molecule 10 NADH molecules and 2 FADH2 molecules are produced. However, when tabulating how much ATP is synthesized, we consider the ATP yield from 8 NADH molecules and 4 FADH2 molecules. Explain why.
The complete aerobic respiration of glucose yields far more energy stored in ATP than glycolysis alone for all of the following reasons EXCEPT: Krebs cycle generates reduced electron carrier molecules (NADH and FADH₂) Krebs cycle generates some additional ATP through substrate-level phosphorylation Electron transport chain (terminal respiratory pathway) produces many ATPs through oxidative phosphorylation using electron carrier molecules (NADH and FADH₂) None of the other four answers (all are reasons that aerobic respiration yields more energy than glycolysis alone) Glycolysis only partially oxidizes the glucose molecule to pyruvic acid
Determine the ATP production of glucose catabolism by glycolysis and Krebs Cycle using the following information: 1. Glycolysis: Net 2 ATP, 2 NADH + H+2. Pyruvate --> acetyl CoA: Produces 2 NADH + H+/glucose3. Krebs Cycle --> 2 FADH2 + 2 ATP + 6 NADH + H+/glucose 2.5 ATP are produced/NADH + H+ delivered electron to the electron transport system1.5 ATP are produced/FADH2 delivered electron to the electron transport system
