Many carbohydrate, lipid and protein food molecules can be used for cell energy. Which scenario best summarizes this?
a.Food molecules are digested into monomers, travel in the blood and within cells their potential energy is converted into another form of chemical energy, ATP
b. Each group of food molecules have their own unique metabolic pathway (aerobic cellular respiration, lactic acid fermentation or alcohol fermentation) any of which make ATP
c. Most food molecules are structurally similar to glucose therefore they participate in cellular respiration without any chemical modifications required
d. Undigested food molecules are delivered to cells via the blood where the mitochondria convert them to ATP.
