- Which of the following statements is true regarding the process of glycolysis? It both requires the input of ATP and produces ATP. It produces ATP by oxidative phosphorylation. It is an alternative to fermentation. It involves changing 1 molecule of glucose into 1 molecule of pyruvate. It occurs in the cell membranes of bacteria.If you are using cellular respiration to get energy from proteins rather than carbohydrates, which of the following is true? there are completely different reactions for protein breakdown as compared to carbohydrates so a different set of pathways is used the amino acids must be broken down into individual C-H or C-C bonds and then those bonds will join with others to create a sugar that enters into the glycolysis pathway O the amino acids are joined with a covalent bond to a sugar and then the hybrid molecule will enter the cellular respiration pathways the amino group is removed and then the rest of the molecule is converted into molecules such as pyruvate or oxaloacetate that can then enter cellular respiration pathways O the amino acids must first be converted into glucose and then they can go through the cellular respiration pathwaysThis process directly uses glucose as an input.
