[Hydrogen ion activity in the cell].

Z A Sorokin

    Tsitologiia
    |July 1, 1976
    PubMed
    Summary

    Cellular hydrogen ion activity is heterogeneous and stable, regulated by protoplasm buffering and active transport. This intracellular pH stability has functional significance, independent of external factors.

    Area of Science:

    • Cell Biology
    • Biophysics

    Context:

    • Intracellular pH (pH) is a critical cellular parameter.
    • Existing models often assume uniform hydrogen ion distribution.

    Purpose:

    • To investigate the distribution and regulation of intracellular hydrogen ions.
    • To understand the stability and functional significance of intracellular pH.

    Summary:

    • Evidence suggests a heterogeneous distribution of hydrogen ions within cells.
    • Intracellular pH represents the mean activity of hydrogen ions across cellular compartments.
    • Cellular pH is resistant to transmembrane potential, metabolic disorders, and external medium changes.
    • pH stability is maintained by protoplasmic buffering and active hydrogen transport.
    • Specific respiratory chains in superficial membranes may be involved in hydrogen release.

    Impact:

    • Challenges the concept of uniform intracellular pH.
    • Highlights the functional importance of stable intracellular pH.
    • Suggests novel mechanisms for cellular acid-base homeostasis.
