<em>The process of cellular respiration begins with </em><u><em>molecules of glucose and ends with production of energy.
</em></u>
<u>Explanation:</u>
<em>Cellular respiration is the process that takes place inside living cells and the initial process is glycolysis.</em> The process of glycolysis breaks down the glucose molecules which contain 6 carbon atoms each into two three-carbon pyruvate molecules.
The output of cellular respiration is energy. The energy produced in cellular respiration is in the form of ATP. <em>Respiration is an exothermic process and two ATPs are produced as a result of cellular respiration. </em>
