Chapter 10, Problem 10.10PS
QUANTITATIVE Oxidation of Saturated Fatty Acids. Calculate the number of FADH2, NADH, and acetyl CoA molecules produced when a molecule of palmitate (16 carbons) is degraded by β oxidation.
(a) Compare that to the number produced from β oxidation of stearate (18 carbons).
(b) Write an equation for the number of acetyl CoA, FADH2, and NADH molecules produced from a fatty acid of n carbons (n = an even number).
(c) Following complete oxidation of the acetyl CoA molecules in the citric acid cycle and electron transport to oxygen, how many ATP will be produced from palmitate and stearate?
(d) Write an equation for the number of ATP produced from complete oxidation of a fatty acid of n carbons (n = an even number).
