In mitochondria, protons are pumped to the ______________ and drive ATP synthesis as they diffuse back into the ______________, while in chloroplasts, protons are pumped into the ______________and drive ATP synthesis as they diffuse back into the ______________
Homework Answers
In mitochondria, protons are pumped to the intermembrane space and drive ATP synthesis as they diffuse back into the matrix, while in chloroplasts, protons are pumped into the thylakoid lumen and drive ATP synthesis as they diffuse back into the stroma.
Both Mitochondria and chloroplast are semi-autonomous in nature can are involved in ATP formation.ATP synthase is involved in ATP formation and is present in both mitochondria and chloroplast. In mitochondria, ATP synthase is present in the inner mitochondrial membrane.

Both mitochondria and chloroplasts use electron transport to pump protons, creating an electrochemical proton gradient, which drives ATP synthesis. Are protons pumped across the same (analogous) membranes in the two oraganelles? Directionality of the pump? Is ATP synthesized in analogous compartments? Fully explain your answers.

1. a. In both mitochondria and chloroplasts, ATP synthesis is coupled to electron transport. Which one of the following is likely to affect the coupling of electron transport to ATP synthesis in both of these systems? Explain. A) the absence of light B) the removal of oxygen C) leucinostatin, an ATP synthase inhibitor D)a photosystem II inhibitor 1.b.

Compare and contrast electron transport and ATP synthesis in mitochondria and chloroplasts. Start with the electron donor and end with the final electron acceptor. Detail the arrangement in the membrane and redox chemistry of the electron transporters, orientation and function of ATP synthase, membrane properties, etc., etc. How are these electron transport systems related to metabolic processes occurring in the mitochondria and chloroplasts?

In mitochondria, a proton gradient is established by the movement of electrons through the electron transport chain. Protons are moved to the intermembrane space against the concentration gradient and the flow back to the matrix via facilitated diffusion using the ATP synthase. Describe how this proton flow contributes to ATP synthesis and the role played by aspartic acid in this process.

11. (13 pts) Electron transfer Electron transfer translocates protons from the mitochondrial matrix to the external medium, establishing a pH gradient across the inner membrane (outside more acidic than inside). The tendency of protons to diffuse back into the matrix is the driving force for ATP synthesis by ATP synthase. During oxidative phosphorylation by a suspension of mitochondria in a medium of pH 6.9, the pH of the matrix has been measured as 7.7....
