Given below are two statements.

Statement I: The process of breathing is very much connected to the process of release of energy from food.
Statement II: The energy required for life processes is obtained by oxidation of some micro-molecules called food.

In light of the above statements, choose the correct answer from the options given below.

Statement I is true. Breathing, which involves the exchange of gases (oxygen and carbon dioxide) between the organism and its environment, is directly connected to the process of releasing energy from food. The energy stored in food (such as glucose and other respiratory substrates) is extracted through cellular respiration, which takes place within the cells of organisms. During cellular respiration, glucose is oxidized in the presence of oxygen to produce carbon dioxide, water, and ATP (adenosine triphosphate). The oxygen required for this process is obtained through breathing.

Statement II is incorrect. The energy required for life processes is obtained by the oxidation of some macro-molecules that we call food.
