The drawings below represent binding sites in two different versions of protein M showing only the Adams in relevant amino acid side chains. Consider a positively charged magnesium ion. Pick the binding site you think is most likely to buy magnesium ion and draw the ion in the binding site showing why is binding in that site.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
