Document Summary

Many chemical reactions that take place in the body, and most of the machinery inside all the cells, are very sensitive to the presence of h+ ions. H+ ions can alter the shape of proteins that act as enzymes that speed up chemical reactions. As a result, any change in the [h+] will affect the activity of almost every cell. Therefore, it is essential that h+ concentration be very carefully regulated. 12. 4 the hydrogen atom and hydrogen ion: the result is an electrically neutral element. The hydrogen atom has a single proton and a single electron. A hydrogen ion (h+) is a hydrogen atom that has lost its electron, leaving only the proton, making it (+) charged. Acid: any molecule that will donate h+ ions when put in a solution: e. g. , hcl (a strong acid) will break apart/dissociate into free h+ and cl-
