![]() ![]() Eventually the electrons will pass to the oxygen. The electrons flow through the electron transport chain and it causes the protons to pump from the matrix to the internal brain space. The givens treatment is France because the electron transport chain and the people in this, these are embedded in the inner mitochondrial matrix. The second statement that is given over here, it says that under anaerobic conditions that is in the absence of oxygen The 80% case this idolized the DP instead of emphasizing it, the right answer for this question is false. This is a combination of large force due to the ph gradient and the smaller force that results from developed voltage gradient across the inner mitochondrial membrane. The first statement it says that the driving force that points the protons into the matrix is called as the proton motive force. The given statements or through our voice. It says that some of the statements are given. You can look up the mathematical equation describing the volume of a sphere in any mathematics textbook.The question that is given over here. Calculate the number of protons in a respiring liver mitochondrian, assuming its inner matrix compartment is a sphere of diameter of 1.5 micrometer.įirst, we need to calculate the volume of the sphere. For spontaneous processes, deltaG is negative, indicating a release of free energy.Ĭ. Why? Because, a concentration gradient will always tend towards equilibrium. Therefore, the outside:inside ratio is simply:Ĭoncentration gradients have free energy inherent in them. Therefore, for the medium, 7.4 = - log Īnd, for the matrix, you do the same thing. During oxidative phosphorylation by a suspension of mitochondria in a medium of pH 7.4, the pH of the matrix has been measured as 7.7. The tendency of protons to diffuse back into the matrix is the driving force for ATP synthesis by ATP synthase. Electron transport translocates protons from the mitochondrial matrix to the external medium, establishing a pH gradient across the inner membrane (outside more acidic than inside). How does the regulation of citrate synthase control the rate of cellular respiration in pig heart tissue? © BrainMass Inc. How does the regulation of citrate synthase control the rate of cellular respiration in pig heart tissue?Ĭ. ![]() Why is succinyl - CoA an appropriate signal for the regulation of the citric acid cycle?Ĭ. On that basis of those observations, suggest how succinyl- CoA regulates the activity of citrate synthase.ī. During oxidative phosphorylation by a suspension of liver mitochondria in a medium of pH 7. When succinyl- CoA is added, the curve shifts to the right and the sigmoid dependence is more produced.Ī. Electron transport translocates protons across the mitochondrial membrane, establishing a pH gradient. In the presence of saturating amounts of oxaloacetate,the activity of citrate synthase from pig heart tissue shown a sigmoid dependence on the concentration of acetyl-CoA. The total free energy available for the phosphorylation of ADP.Ħ. The percentage of energy from the chemical (pH) gradient and the percentage from the charge gradient.Ĭ. The protonmotive force across the inner mitochondrial membrane at 25 degree celsius when the elcetrical difference is -0.18 V (inside negative), the pH outside is 6.7, and the pH inside is 7.5.ī. Calculate the number of protons in a respiring liver mitochondrian, assuming its inner matrix compartment is a sphere of diameter of 1.5 micro meter.Ī. ![]() What is the outside: inside ratio of ? Is there energy inherent in this concentration? Explain.Ĭ. Calculate in the external medium and in the matrix under these conditions.ī. During oxidative phosphorylation by a suspension of mitochondria in a medium of pH 7.4, the pH of the matrix has been measured as 7.7.Ī. Electron transport translocates protons from the mitochondrialmatrix to the external medium, establishing a pH gradient across the inner membrane (outside more acidic than inside).
