The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain. Choose all that apply.Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. The reactions of the ETC take place in the outer membrane of mitochondria. Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Electrons generated...

1. Where, specifically, is the Electron Transport Chain (ETC) of cellular respiration located within the cell? 2. What do the “taxi” molecules from glycolysis and the citric acid cycle do with their electrons when they reach the ETC? 3. What happens, physically, to the electrons in the electron transport chain? 4. What happens, in terms of energy, as electrons move through the electron transport chain?

1. (a) If the disaccharide lactose is hydrolyzed into monosaccharides, how will the products enter the glycolysis pathway? To show this, draw the full structure of lactose and show how it is hydrolyzed and the steps required for the products to be metabolized in the glycolysis pathway. For each synthetic step, write the name and draw the structure of reactant(s) and product(s), indicate any cofactors, and name the enzymes required. (Include final product for each (is, the glycolytic intermediate) and...

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
