In the breathing process, the lungs take in oxygen from the air through inhalation. Carbon dioxide produced by cellular respiration is in turn released through exhalation. This process requires energy and is therefore a type of active transport.

Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
