Hey guys - first year medic here
So I understood this at A level in terms of the fat being in a more reduced state with fewer oxygens than carbohydrates so electrons with C-H bonds being at a higher energy state than C-O bonds such as in glucose hence when you burn fats the calorie yield is higher.
When I apply this to the actual yield of energy in our bodies, in terms of ATP, I really don't understand this logic as ultimately surely it doesn't matter about how reduced fats are as due to beta oxidation the fatty acids just produce many acetyl CoA molecules which enter into the Krebs cycle hence isn't the actual yield of energy of fats higher than carbohydrates simply due to fats having longer carbon chains hence can produce more ACoA per fat molecule (as well as glycerol producing G-3-P) hence a fat molecule can produce more ATP than glucose?
Cheers in advance
