Calculate the ATP yield for the complete oxidation of one molecule of palmitic acid (16 carbons). How does this figure differ from that obtained for stearic acid (18 carbons)? Consider the b-oxidation steps, processing of acetyl-CoA through the citric acid cycle, and electron transport.
Answer to relevant QuestionsDescribe briefly how b-oxidation of an odd-chain fatty acid is different from that for an even-chain fatty acid. A friend who is trying to lose weight complains about the odd taste in his mouth in the mornings. He says it seems like a filling has broken loose, and the metallic sensation is bothersome. What would you say? Draw a six-carbon saturated fatty acid and show where the double bond is created during the first step of b-oxidation. What is the orientation of this bond? Why do we describe the path of electrons in photosynthesis as starting in photosystem II and ending in photosystem I? In other words, why is the nomenclature “backward”? List three ways in which the structure of chlorophyll differs from that of heme.
