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...

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,...

Imagine that you've just discovered a new microbe with an ATP synthase that is very efficient. As such, it takes only 2 H+ to make 3 ATP molecules. Now you want to know-how many ATP molecules will this organism produce when it completely oxidizes 1 molecule of glucose? Assume that 10 protons are pumped across the inner membrane for every NADH molecule, while 6 protons are pumped for every FADH2. How many ATP molecules would this organism produce when it...

Part 1: For every NADH oxidized to NAD, how many protons are transported to the intermembrane space to the mitochondria? Part 2: How many protons are necessary for the synthesis of one ATP? Part 3: How does each of these protons contribute to the synthesis? Part 4: Using your answers from the previous two questions, prove that 25 ATP can be formed from oxidation of 1 NADH.

C. Considering Electron Transport: In LA3 Video 3, we are considering electron transport and oxidative phosphorylation. Please answer the following multiple choice questions (0.5 pts each) and follow instructions for two final drawings (2 pts each). 1. The electrons involved in electron transport come from (A) glycolysis (B) the pyruvate dehydrogenase complex (C) the citric acid cycle (D) all three processes 2. When NADH and FADH2 transfer their electrons to the electron transport chain, they are (A) oxidized (B) epimerized...

8. The movement of protons out of the mitochondrial matrix establishes an electrochemical H gradient across the inner mitochondrial membrane. The electrochemical potential of this gradient is harnessed to synthesize ATP. This is known as the (A) Hydrophobic effect IqChemiosmotic theory (B) Acid catalysis (0) Michaelis-Menten mechanism _9. Which of the following statements about mitochondria and their lon and metabolite transporters is FALSE? (A) Controlled impermeability of the inner mitochondrial membrane to most ions and metabolites allows for the generation...
