1. There's a branching point in cellular respiration involving pyruvate. Pyruvate can undergo lactic acid fermentation or enter the mitochondria to enter the citric acid cycle. What determines what happens to pyruvate? A. Energy demands of the cell B. 15% concentrated power of will C. pH of the intracellular fluid D. Presence/absence of oxygen In the fed state, how is glucose used in the body? Select all correct answer choices. A. Used in glycogenesis to create glycogen in skeletal muscles...

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,...

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...
