It will all make more sense if you start from the beginning of the sequence with the structure of DNA. You will remember that messenger RNA contains a sequence of bases which, read three at a time, code for the amino acids used to make protein chains. Each of the sets of three bases is known as a codon.
I recall that Professor Kwang had observed amoebas that had cannibalized bacteria cells. The bacteria were slaughtering the amoebas, but somehow some survived. This particular group of amoebas contained bacteria that thrived inside it. Hence the name, endosymbiosis. However, this lucky group and it's offspring could not survive without bacteria.
The result of this treatment will decrease the osmotic pressure of the blood, causing the cell is losing water molecule by osmosis.
Administering pure water as resuscitation fluid might also lower the concentration of electrolyte in the blood, causing electrolyte imbalance. It is recommended to use normal saline(0.9% NaCl) solution for resuscitation as the solution is having the same osmotic pressure, thus won't inducing osmosis.
