    1. To maintain a constant pH environment inside the living system by resisting the sudden changes in the concentration of H⁺ ions
    2. To keep a steady number of carrier protein molecules in the unit membranes
    3. To enhance the production of higher number of H⁺ or HO⁻ ions inside a lysosome of a cell
    4. To resist a sudden rise in the CO₂ gas molecules inside the mitochondria of a eukaryotic cell
    5. To maintain a constant salt concentration inside a cell
    1. The living cells can survive the drastic changes in the pH of the system without a buffering system
    2. pH homeostasis is a crucial system for the survival of a biological system
    3. Proteins act as excellent intracellular buffers due to their capability to take up both H⁺ and HO⁻ ions
    4. The biological buffers help in maintaining pH homeostasis by picking up or releasing the H⁺ ions
    5. The blood acidity increased by the CO₂ production via cellular respiration is compensated by bicarbonate buffer system in the humans

    great teacher
    By Dinara Z. on 12. August 2018 for Ph Homeostasis – How Atoms Come Together to Form a Molecule

    great lecture, very simple and clear. I've finally understood bonds!)) thank you!

     
    GREAT LECTURE
    By ANNA S. on 01. June 2018 for Ph Homeostasis – How Atoms Come Together to Form a Molecule

    VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT

     
    Superb lecture!
    By Christmas P. on 30. January 2018 for Ph Homeostasis – How Atoms Come Together to Form a Molecule

    The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!
