Does ATP cross the cell plasma membrane

I H Chaudry

    The Yale Journal of Biology and Medicine
    |January 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Cells can release and take up adenosine triphosphate (ATP), a key energy molecule. This review highlights evidence that ATP can indeed cross cell membranes, challenging previous assumptions and indicating these are normal physiological processes.

    Area of Science:

    • Cell Biology
    • Biochemistry
    • Physiology

    Background:

    • The transport of adenosine triphosphate (ATP) across cell membranes has been a subject of debate.
    • Prevailing views suggested that ATP, a crucial cellular energy currency, could not permeate the cell membrane.

    Purpose of the Study:

    • To review and consolidate evidence regarding the release and uptake of ATP by cells.
    • To address the prevailing concept that ATP cannot cross the cell membrane.

    Main Methods:

    • Literature review of studies investigating cellular ATP transport.
    • Analysis of experimental data from various investigators on ATP release and uptake.

    Main Results:

    • The reviewed evidence strongly indicates that ATP can cross the cell membrane.

    Related Experiment Videos

  • Multiple studies support the bidirectional movement of ATP into and out of cells.
  • Conclusions:

    • The release and uptake of ATP by cells are physiological processes.
    • The ability of ATP to cross cell membranes is supported by substantial scientific evidence.
