Document Summary
Many chemical reactions that take place in body, and most of the machinery in cells are. Module 12 acid and bases sensitive to presence of h+ H+ can alter the shape of proteins that act as enzymes that speed up chemical reactions. So, any change in the concentration of h+ will affect the activity of almost every cell. So it is important that h+ concentration be regulated carefully. An acid is any molecule that will release hydrogen ions when put in a solution: ex: hcl. Will break apart (dissociate) into a free hydrogen ions (h+) and chloride ions (cl-) A base is any molecule that will accept a hydrogen ion: ex: hco3- Bind with h+ to form carbonic acid (h2co3: bases lower the concentration of free h+ in solution by combining with the h, less free h+, acidity decreases and becomes more basic or alkaline. Ph scale is a way of quantifying the concentration of h+ in any solution.
