Answer Posted / rohan sharma
as an antiseptic, 70 percent of alcohol is prefered to a
stonger solution. Pure alcohol coagulates protein in
contact. Suppose the pure alcohol is poured ovr a single
celled organism. Th alcohol will penetrate the cell wall of
the organism in all direction, coagulating the protein just
inside the cell wall. the ring of the coagulated protein
would then prevent the alcohol from penetrating farther from
the cell, and no more coagulation woul take place. At this
time the cell would become dormant butnot dead. under the
proper condition the cell would then begin to function. if
70 percent of alcohol is poured to a single celled organism,
the diluted alcohol also coagulates the protein, but at a
slower rate, so that it penetrates all the way through the
cell before coagulation can block it. then all the cell is
coagulated and the organism dies.
