Students have asked these similar questions
a.Write the balanced reactions catalyzed by complex I, II, III, and 1V, and using these, write the balanced net
reaction for the electron transport chain. Structures are not necessary.
b. Write the balanced reaction for the ATP synthase reaction.
c. Write the net reaction for Oxidative phosphorylation showing the ATP produced from NADH oxidation and
FADH2 oxidation. (this is in your text)
d. Write the balanced reaction for ATP production by aerobic metabolism starting with glucose.
. VISUAL SKILLS Name the molecules that conserve mostof the energy from the redox reactions of the citric acidcycle (see Figure 9.12). How is this energy converted to aform that can be used to make ATP?
Remember for T/F questions, either answer TRUE or FALSE, but if the answer is FALSE make sure to explain WHY the answer is false.
The cell prefers lipids as a food source due to the large amount of NADH it can create during fatty acid oxidation is then used to create ATP.

- Prelab 8 - Respiration You have learned that in glycolysis and the Kreb's cycle, the compound NAD is reduced to form NADH. The hydrogen added on the end of the formula is an indication that NAD has been reduced. As you read in the textb0ook section on oxidative phosphorylation, a series of redox reactions oxidize NADH back to NAD. All redox reactions are paired oxidation and reduction reactions, so what was reduced? Ultimately O2 is reduced to H2O (note the addition of hydrogen due to reduction). Oxygen is said to be the final electron acceptor, as no further redox reactions take place. In lab we will again look at differences among bacteria in their metabolism as a way to distinguish different species. First we will look at anaerobic respiration. When oxygen levels are low, some microbe can use a different compound than oxygen as their final electron acceptor. Sulfate SO,, carbonate CO3²", and nitrate NO; are all common alternatives, rich in oxygen, which can accept those electrons.…arrow_forwardTopic : Connection between Electron Transport & Phosphorylation Task: 1.
