By number, identify all of the following four statements that accurately describe the processes involved in aerobically producing ATP: 1) Although prokaryotic [proh-KAR-ee-oh-tik] cells lack mitochondria [my-tuh-KON-dree-uh] and cristae [KRIS-tuh], they use a proton pump to produce ATP; 2) Energy is liberated when the chemical bond between ATP and its phosphate subgroup is formed; 3) Oxygen is used in the last step of aerobic respiration to produce water; 4) Chemiosmosis produces more ATP molecules than oxidative phosphorylation [FOS-fer-uh-lay-shuhn].
