Waste products in the cell accumulate and are eventually moved out of the cell and eliminated. taken to the mitochondria and used as energy. released into the cytoplasm of the cell. brought to the nucleus and made into dna.

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.
