How are breathing and cellular resperation similar?

Cellular respiration is directly related to breathing, as breathing provides the necessary oxygen molecules for the process of cellular respiration to take place; cellular respiration is a process by which cells acquire energy. The oxygen provided by breathing is used as a final hydrogen acceptor for the process.

During inhaling, the oxygen necessary for cellular respiration is provided. During the exhale, the carbon dioxide that is produced by cellular respiration leaves the body. The relation between breathing and cellular respiration is critically important because without either one of the processes, the other cannot occur
