3, Describe the process of oxidative phosphorylation, as completely as possible. In your description, include the terms NADH, FADH2, ATP, mitochondria (or mitochondrial), glycolysis, Kreb's cycle, electron (or electrons), proton (or protons), and oxygen. In your description, account for how ATP molecules get produced, and how many ATP molecules are produced per FADH2 and NADH (note: NADH from outside the mitochondria generate a different number of ATP compared to NADH inside the mitochondria.

EVOLUTION LINK The reactions of glycolysis are identical in all organismsprokaryotes, protists, fungi, plants, and animalsthat obtain energy from glucose catabolism. What does this universality suggest about the evolution of glycolysis?
3. A recently discovered mutant yeast has a shorter glycolytic pathway, and with a new enzyme that catalyzes the reaction: Glyceraldehyde-3-P + H₂ + NAD+ ‒‒‒‒‒‒> 3-phosphoglycerate + NADH+H* Would shortening the glycolytic pathway in this way benefit the cell? Explain. Consider metabolic outcomes only in anaerobic conditions.
4. Who’s on first? Although both hexokinase and phosphofructokinase catalyze irreversible steps in glycolysis and the hexokinase-catalyzed step is first, phosphofructokinase is nonetheless the pacemaker of glycolysis. What does this information tell you about the fate of the glucose 6-phosphate formed by hexokinase?
3. Distinguish the correct statements about oxidative phosphorylation. I. 1 poir Oxidative phosphorylation generates ATP by transferring phosphate group directly to ADP molecule. II. Oxidative phosphorylation occurs inside mitochondria and the source of energy is from sunlight. II. Oxidative phosphorylation occurs inside mitochondria and the source of energy is from glucose. IV. Oxidative phosphorylation is based on electrons moving through ETC and production of a proton-motive force that drives ATP synthase. A. I & II O B. I & II O C. II & IV D. III & IV pc FATD
Describe the process of oxidative phosphorylation. In your description, include the terms NADH, FADH2, ATP, mitochondria (or mitochondrial), glycolysis, citric acid cycle, electron (or electrons), proton (or protons), and oxygen. Be sure to describe how ATP molecules get produced, and how many ATP molecules are produced per FADH2 and NADH (note; NADH from outside the mitochondria generate a different number of ATP compared to NADH inside the mitochondria; your description should indicate both quantities for full credit.) vas 19llo ton lle vowor 1esb
2B. Calculate the total number of ATP that will be generated from the complete B-oxidation of oncobic acid (CH:(CH,),CH=CH(CH,),COOH; 15:1 cis-A9) in an organism that has all the standard required enzymes for metabolism but which pumps only 2 H" in complex I, 0 H' in complex II, 2 H* in complex III and 4 H' in complex IV. The F,F, ATPase is composed of 3 a/ß subunits and 10 c subunits. Show all of your calculations. HO
2. Please, determine the answers of these multiple choices, they’re in a,b,c’s. A) The role of oxygen in oxidative phosphorylation (cellular breathing) is: -To be the last electron acceptor in the electron transfer chain -To hydrolyse carbohydrates - To add hydrogen ions to pyruvic acid at the end of glycolysis -To provide electrons for NADP reduction -To provide hydrogen ions B) Which molecule has the most potential energy? -glucose -phosphate -fructose 1-6 diphosphate -ethanol -I'ATP C) What is the product of fermentation in yeasts? -carbonic acid -oxygen -ATP -lactic acid -ethanol
1. In living organisms, can metabolism yield a ΔG with a value of "0"? Please explain. 2. Where does citric acid cycle take place (please be very specific)? 3. What is substrate-level phosphorylation? What is the percentage of energy generated by substrate-level phosphorylation during aerobic phosphorylation? 4. In electron transport chain (aerobic respiration), which molecule is the most electronegative (highest electronegativity)?
10. The reaction for cellular respiration is exergonic (AG = -2870 kcal/mol) but only produces 32 ATP per molecule of glucose, representing an energy total of AG = +976 kcal/mol. What can explain this discrepancy? A. One molecule of glucose produces 2 pyruvate during glycolysis and cellular respiration therefore produces a total of 64 ATP. This makes up for the difference in energy converted from glucose to ATP. B. Both NADH and FADH₂ are also produced and contribute to some ATP, on top of the 32 ATP already produced. C. Energy remains in some glucose molecules that are not yet oxidized. D. Energy is lost in the form of heat. E. Cellular respiration includes some endergonic reactions that make up the difference in energy converted from glucose to ATP.
4) What are the different components of the electron transport chain, where are they situated in cells? Write down the ultimate electron donor and acceptor for each component. How is the released free energy immediately stored during each of these oxidation-reduction reactions (as the reactions are executed)?
30. Runaway mitochondria 1 . Suppose that the mitochondria of a patient oxidize NADH irrespective of whether ADP is present. The P : O ratio for oxidative phosphorylation by these mitochondria is less than normal. Predict the likely symptoms of this disorder.
3. Explain the total (net) yield of ATP from Aerobic respiration in three of the different stages of cellular respiration (Glycolysis, Krebs Cycle and Electron Transport Chain). Pyruvate oxidation or the Link reactions does not make ATP. In other words, how many total ATP energy molecules are produced in each cycle and which steps in the different cycles make the ATP. Explain the yield in reference to the overall cellular respiration Equation.
