Which of the following statements are true? 1-electron carriers are located at ribosomes. 2-atp is a common intermediate between catabolic and anabolic pathways. 3-atp is used for the long-term storage of energy and so is often found in storage granules. 4-anaerobic organisms are capable of generating atp via respiration. 5-atp can be generated by the flow of protons across protein channels.
