Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration. Oxygen combines with electrons and hydrogen ions to produce water. Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules. True False

Step 1
The first step of cellular respiration is glycolysis, where glucose is broken down into two molecules of pyruvate. This process occurs in the cytoplasm of the cell and does not require oxygen. Show more…

Cell Respiration
Answer the following parts below: a) During aerobic respiration the terminal electron acceptor is ______ which will eventually produce a molecule of ______. Group of answer choices (pick 1) CO2; O2 NAD+; NADH O2; CO2 ADP; ATP O2; H2O b) In aerobic cellular respiration, what is the "big picture" significance of the first three steps of the process? Group of answer choices (pick 1) They produce water for the cell They allow for the production of glucose for the cell They generate lots of ATP through substrate level phosphorylation They allow for electrons and protons to be collected for use in the electron transport chain They generate terminal electron acceptors
