Document Summary
If you live in hypoxia and rely on anaerobic glycolysis to survive, you can pollute your body with a lot of acid, so you have to deal with that acid. You can increase the buffering capacity of your tissue to deal with ph. On the intracellular level, the most important buffer is phosphate buffer saline. H2po4- h+ + hpo42-: eq"m rxn with ph near 7. If too acidic (thus a lot of h+), then phosphate buffer can consume these protons and balance ph back. Animals that rely on anaerobic glycolysis tend to have more of these phosphates within their cells. Outside of cells, you can also mobilize some other buffers from other parts of the animal (like carbonate (co3)) Carapace of shell is made mostly of caco3 (bone is capo4), and co3 can be a good buffer (caco3 ca2+ + co32- , then co3 can combine with h+ to form hco3- within the blood)
