- 6. Electron movement results in the establishment of a proton gradient across the inner mitochondrial membrane. The proton motive force then provides the energy for ATP formation. a. How are protons shifted from the matrix to the intramembrane space? b. How is the proton gradient harnessed for ATP formation? c. How does ATP reach the cellular compartment/s where biosynthesis is occurring?

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.

The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...

In cellular respiration, as a result of the electron transport chain, a proton gradient is established. Where in the cell are the protons concentrated? In the intermembrane space, between the inner and outer membranes of the mitochondrion Between the outer membranes of the mitochondrion and the plasma membrane Between the plasma membrane and the cell wall Between the plasma membrane and the extracellular matrix In the inner membrane of the mitochondrion

1. 2,4-Dinitrophenol (DNP) is a molecule that can shuttle protons across cellular membranes and was used in diet pills in the 1930s (but was quickly discontinued for its lethality). Explain how this molecule might induce weight loss, and why its consumption is often fatal. 2. Biosynthesis and breakdown of glucose share many common enzymes and reactions, but this is not the case in the metabolism of fatty acids. Compare and contrast fatty acid biosynthesis vs. beta-oxidation (location, acyl group carriers,...
