- Energy 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_forwardExplain the process of electron transfer phosphorylationarrow_forward
- Explain why compounds such as cyanide that disrupt the electron transport chain are poisonsarrow_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_forwardExplain 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_forward
- Please describe the function of the Electron Transport Chain.arrow_forwardList the products of linear electron transport and cyclic electron transport, and describe the role of cyclic electron transport.arrow_forwardElectrons are continuously transferred from higher-energy carriers to lower-energy carriers in the electron transport chain, yet somehow iron is utilized as an electron carrier multiple times. Choose the most likely reason why this is possible. The pH of complex II is slightly higher than the pH of complex III. The reduction potential of flavin mononucleotide (FMN) in complex I is higher than the reduction potential of iron. The redox potential of iron ions can be manipulated by their environment. For instance, the iron in an iron-sulfur cluster will have a different redox potential than the iron in a heme group. The electrons carried by NADH are higher energy than the electrons carried by FADH2.arrow_forward
