Provide a simplified schematic presentation of mitochondrial β-oxidation. Include activation, mitochondrial transportation, important coenzymes and enzyme names. (Note that you can simply provide intermediate names or abbreviations here and not structures).
Draw and label a lipid bilayer containing the large mitochondrial trans-membrane protein complexes representing complex I, II, III, and IV, and ATP Synthase. Label your diagrams with the correct names for the membranes, Make two more of these drawings. Label the first one mitochondrial electron source and using a different ink color, indicate the source(s) of electrons. Label the second mitochondrial energy source, and indicate the source of energy driving the electron transport chain. In the third, label the mitochondrial electron acceptor in its proper position. Also include ATP synthase (in its correct orientation-the spherical part is on the opposite side of the membrane as the H+ reservoir). Use a different color of ink to show where the protons (H+) are pumped to drive ATP synthesis. also indicate where ATP is generated and were the power is stored to generate ATP. NOW, do the same thing with chloroplasts. Draw and label a lipid bilayer containing the large photosynthetic…
Amytal is a barbiturate sedative that inhibits electron flow through Complex I. How would the addition of amytal to actively respiring mitochondria affect the relative oxidation–reduction states of the components of the electrontransport chain and the citric acid cycle?
Give only typing answer with explanation and conclusion In the presence of oxygen, the oxidation of NADH has a ΔG of -50 kcal/mole and FADH2 has a ΔG of -40 kcal/mole. The production of ATP from ADP has a ΔG of + 10 kcal/mole. Given these values, if cellular respiration is working at an efficiency of 25%, how many molecules of ATP will be produced/molecule of glucose. Assume all NADH and FADH2 enters the electron transport chain.
