A student in science class is asked to sketch a basic model of an animal cell using only three essential features. The student must select the most crucial organelles to draw for a new student to understand the basic structure of an animal cell. Which of the following structures would be best to include in this basic model? (DOK 2)

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.
