You eat a chocolate bar to get you through a late-night studying session. your body quickly begins to break down the macromolecules in the candy, using the sugars, lipids, and protein to make atp. which of the following is not a step in the process of breaking down the candy bar's macromolecules? a. first step: the sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-coa molecules. no energy is produced in this first step. b. second step: glycolysis converts the glucose to two molecules of pyruvate. six atp molecules are produced in this step. c. third step: oxidation of each pyruvate produces two molecules of acetyl-coa. six atp molecules are produced in this step. d. fourth step: two acetyl-coa molecules go through the krebs (citric acid) cycle. twenty-four atp molecules are produced through this process. e. all of the above steps are part of the break down of the candy bar's macromolecules.
