Would you expect to encounter difficulties in determining the number of protons pumped in electron transport across the thylakoid membrane?

- Sketch the double-membrane system of the mitochondrion and show where electron transfer chains and ATP synthases are located.arrow_forwardHow is the function of the thylakoid membrane similar to that of the inner mitochondrial membrane?arrow_forwardWould you mind explaining the Electron Transport System how you understand it? Explanation: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water. Question: Respond to the Explanation post above about the electron transport chain.arrow_forward
- Examine Figure 11-13. Where are the electron carriers of the mitochondrial electron transport chain located— in the matrix, the membrane, or in the crista lumen? As they carry electrons, some of them also deposit protons (H+). Are the protons deposited in the matrix or in the crista lumen?arrow_forwardThe maintenance of a proton motive force across the inner mitochondrial membrane is crucial for continued ATP production. Surprisingly, it has been discovered that the inner membranes of certain cells contain proteins, called uncoupling proteins, that are capable of transporting protons from the intermembrane space to the mitochondrial matrix. Why would mitochondria contain transporters that essentially waste energy potential in the proton gradient?arrow_forwardRead all the parts of this question before answering. Thermogenesis is a metabolic process used to generate heat in many homeothermic/endothermic/warm-blooded animals and a few species of plants. Thermogenesis involves an uncoupling protein that allows protons to flow from the intermembrane space back into the mitochondrial matrix. a. What two processes – which are normally energetically coupled – become uncoupled by the action of uncoupling proteins? b. What kind of a protein allows ions such as H+ to diffuse through a membrane?arrow_forward
