Aerobic respiration. Definition. noun. (1) A form of cellular respiration that requires oxygen in order to generate energy. (2) The process of generating energy by the full oxidation of nutrients through Krebs cycle where oxygen is the final electron acceptor.
Aerobic Respiration, meaning 'with oxygen' which is used for long-term, steady paced exercise and day-to-day activities and Anaerobic Respiration or 'without oxygen' which produces fast bursts of energy for short, powerful bursts. The Anaerobic system can be divided into two further systems, ATP-PC and Lactic acid.All energy systems work together, but the intensity and type of activity will determine which system is predominant. 1  Aerobic system. 2  Anaerobic system. 3  ATP-PC system. 4  Lactic Acid System.he Anaerobic system can be divided into two further systems, ATP-PC and Lactic acid.
