- PFor each of the following experiments, tell me whether you would expect the rate of O₂ consumption and ATP synthesis to increase, decrease or remain the same (respectively). Assume there is plenty of O₂ around. (a) Succinate is suddenly added to mitochondria that have no other oxidizable substrates (Assume that there are ADP and Pi in mitochondria). (b) ADP is not allowed to pass into the mitochondrial matrix. (c) 2,4 Dinitrophenol (an uncoupler) is added.arrow_forwarda) Make a theoretical calculation of how many ATP molecules can be formed from the breakdown of a molecule of Acetyl- CoA into carbon dioxide and water. The prerequisite is that the entire proton gradient across the mitochondrial inner membrane can be used for ATP production and that the ATP synthase has 6 c-subunits.arrow_forwardGive answer of all three subparts with explanation!arrow_forward
- Mitochondria are critical for normal metabolism. From which parent did each human being’s original mitochondria come from at conception? In Luft’s syndrome the mitochondria are not producing sufficient amounts of ATP. What series of reactions could be most responsible for the deficiency? What are some other conditions that are thought to involve mitochondrial malfunction? What's your opinion on the 3-parent babies technique approved in the UK?arrow_forwardA central tenet in mitochondrial bioenergetics is that exergonic electron transfer drives the creation of an electrical potential () across the inner mitochondrial membrane (IMM). This is entirely true. Another tenet of mitochondrial bioenergetics, that you will read everywhere, is that this electrical potential is created by three proton pumps, Complexes I, III and IV. This is less true. A proton pump is this: It’s a protein that binds a proton from one side of a membrane, translocates that very proton across the membrane, through the protein, and ejects it into solution on the other side of the membrane. Complex I is a proton pump, but we did not discuss complex I. Complex III is NOT a proton pump, yet it creates electrical potential across the IMM. It is an electron/proton charge separation device. Complex IV is both types of these devices. Fifty percent of the electrical potential that complex IV creates is as a proton pump. But, 50% of the electrical potential that complex IV…arrow_forwardRationalize why 4 (and not 5 or 10) protons are transferred from inside to outside of the mitochondrial inner membrane by the Complex I? (Hint: use redox potential of NADH and Ubiquinone, mitochondrial membrane pH =0.75 units, and the potential difference across the inner mitochondrial membrane = 0.15V) For the purpose of energy utilization, what are the advantages of generating energy from lipids as compared to that of carbohydrates?
