    What does it mean to move down an electrochemical gradient

    • @dannichols6261
      @dannichols6261 4 года назад +5

      To answer your question, we first need to understand *electrochemical* & then *gradient* .
      1. Electro-chemical refers to a volume of space containing *ions* of *chemicals* . Chemicals are atoms of elements, or molecular combinations of elements. Ions are parts of chemicals which have lost or gained electrons, thus conferring a *charge* to them.
      2. A *gradient* is a differential distribution of any substance (more of a substance in one place and less in another).
      3. To move *down* a gradient is to move *from* a place of high concentration, *to* a place of lesser concentration.
      4. To specifically move down a *chemical* gradient, is to move from a place of more concentration of a *chemical substance* to a place of less of that chemical substance, by diffusion (because at anything other than absolute zero, all molecules are in kinetic motion, either bouncing off one another, or at least just 'vibrating').
      5. Alternatively, to move down an *electrical* gradient is to move from a place of *high charge* to a place of *lesser* charge, by repulsion of like charges.
      6. So moving down an *electrochemical* gradient is a *combination* of the two, such that *chemicals* will move to attempt to equalize the concentrations of those chemicals within a space, but any imbalance of *charges* caused by that movement will force some of the charged ions *back* against the *chemical* gradient.
      7. The result would be a *balance* between the molecules' attempts to equalize the chemical concentration, and the forces of the electrical charges.
      8. A better explanation might be: en.wikipedia.org/wiki/Electrochemical_gradient

    my prof uses donna equilibrium to explain why the inside of the cells is negatively charged, while showing each compartment in electrical neutrality. so i was pretty confused, so does a lot of videos on yt. can you explain why they're using that example? like the only thing i got from that is, one of the compartment has higher oncotic pressure.
