Re: Is their a name for the process by which acids deteriorates algae cells?

Dear Hammad: You should not think of acid wearing away a cell as it might a
piece
of metal... the acidity is not that great and the response of the cell
is too fast.  Rather, acidity probably harms the plant cell at two
different sites.  The first is at the plasma membrane.  Plant cells
use alot of energy to pump protons out of the cell.  This
unidirectional movement of protons creates an electrochemical gradient
(the inside of the cell is more negative because positive charges
(protons) are being pumped out). The effect of high external acidity
would be to collapse this electrochemical gradient.  This
electrochemical is vital to the cell's health because the potential
energy it represents is used to co-transport other chemicals (amino
acids, sugars, ions and carbonate) into the cell.
The second site of potential injury is the chloroplast, the photosynthetic 
organelle.  There, the energy of the sun is used to
create a pH gradient across the inner membrane of the chloroplast.
This pH gradient is used to make a very important compound called ATP.
This ATP is used in producing sugars from CO2. So, what would one call
this process???? Intracellular acidification, I suppose.
