    A fresh supply of oxygen must be constantly provided so that cells are able to metabolize glucose efficiently.
    The constant production of carbon dioxide by cells must be constantly removed from the body.
    Because respiration, also called breathing, is synonymous with cell respiration.
    all of the above
    Both the first and second answers are correct.
