Document Summary

If it isn"t glucose, how do we get energy from it: glucose is preferred choice. Cellular respiration is central to catabolism. o. Fats and proteins feed into different points: proteins. Go into pyruvate, acetyl coa, and cac o. Energy is captured during the conversion of fatty acids to acetyl coa. o. Easier to break: occurs in the mitochondrial matrix. Fatty acid conversion to acetyl coa by beta-oxidation is associated with energy capture o. Fatty acid w coa attached to it at the end. In mitochondria: oxidizes one of the carbons. Captures electrons in fadh: oxidize next one and add another coa, nadh come out. Every time cycle goes around, it generates a single 2-c molecule (acetyl coa): cycle will generate n/2 acetyl coa molecules. N = number of carbons in the chain: cycle will run n/2-1 times. 10 nadh x 2. 5= 25 atp 2 fadh2 x 1. 5 = 3 atp.
