Many nucleic acid forms a polymer known as (a) . (Note: Acronym (CAPITAL) or word (small)
carbonic anhydrase is present in three cells except in:
Gastric parietal
Plasma
Red Blood
Renal tubular
Plasma Membrane
occurrence in hydrolysis
monomers are released by the addition of a water molecule, adding OH to one monomer and H to the other
monomers are joined by removal of OH from one monomer and removal of H from the other at the site of bond formation
reverse process: polymers are broken down or digested to their monomers
the water molecule is added to each bond, bond is broken, releasing the monomers
