- Explain in detail the concept of cyclic electron transport.arrow_forwardEnergy is required to reverse the flow of the electron transport chain. Why would this be so?arrow_forwardA proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced. This is an example of A) energy coupling B) cotransport C) allosteric regulation.arrow_forward
- Explain the Electron transport chain in detail.arrow_forwardModels such as the one shown in the illustration below are often used to represent the electron transport chain. Explain why this model is well-suited to this concept. Explain why metabolic processes such as cellular respiration and photosynthesis require a multi-stage release of energy, rather than a one-step reactionarrow_forwardExplain the process of electron transfer phosphorylationarrow_forward
- explain the relationship between the following structures (cell cytoplasm, mitochondria, krebs-cycle, electron transport chain).arrow_forwardExplain why compounds such as cyanide that disrupt the electron transport chain are poisonsarrow_forwardWhich of these molecules associated with electron transport is in the reduced state? Choose from the following: (A) cytochrome a3+++ (b) cytochrome a3++arrow_forward
- Explain why oxygen is not needed in glycolysis but is in the electron transport chain. How is water formation related to the role of oxygen in the electron transport chain?arrow_forwardWhich of the following can be by-passed; i.e., other means of introducing electrons into the electron transport chain without using this complex are available? Complex V Complex II Complex III Complex IV Complex Iarrow_forwardThe following statements describe the path of electrons from NADH through the electron transport chain. Please arrange them in order: Cytochrome c (Fe2+) carries electrons to Complex IV. Cytochrome c (Fe3+) is reduced to cytochrome c (Fe2+) QH2 carries electrons to Complex III Oxygen is reduced to water Ubiquinone (coenzyme Q) is reduced to ubiquinol (QH2)arrow_forward
