1.Identify the end products of protein digestion that made up the contents of test tube B after the two hours. 2.State what the result would be if the same enzyme that was added to test tube B was added to a test tube containing starch. Support your answer.

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.
