Determine how many molecules of glucose is needed for 1 molecule of palmitate (C16). Assume that all NADPH consumed in this process is also produced from glucose using the pentose phosphate pathway in which all glucose 6-phosphate entering the PPP is converted to CO2, , H2O, and NADPH (no ribose 5-phosphate is formed). Required ATP should also be synthesized from glucose.
