The Immediate Energy System in skeletal muscle utilizes several integrated chemical reactions to liberate energy for cellular work in an explosive, rapid sequence, but then quickly put the ATP back together again. The aerobic system is the most utilized of the three. Anaerobic metabolism produces lactate. Non-Oxidative Energy Sources. The non-oxidative energy systems pale in comparison to the ability of the oxidative energy system to rephosphorylate ATP and reduce the hydrogen threat inside the body. The oxidative system copes with lower output work for longer durations of time–such as a road race. The oxidative energy system produces ATP in structures called a. alveoli. 20. Anaerobic Metabolism (Anaerobic-Glycolitic) is the non-oxidative process of recycling of ATP from glycogen. After approximately 2 minutes, the body shifts to the final energy system. Once CP is depleted, other energy systems must assist in the ATP generating process. Oxidative Pathway for Energy Production. Energy System 3: Oxidative (Aerobic) System The first or third system is the Oxidative phase. Target heart rate zone is from 50% to 70% of maximum heart rate. It provides energy for low intensity activities that last anywhere from two minutes to a few hours. False. Energy System #3: Aerobic Oxidative System. The oxidative system is a relatively slow system for producing ATP and only works in the presence of oxygen. The energy system that uses ATP and creatine phosphate fuels the body for long exercise sessions. The Immediate Energy System. c. 3–5 minutes. Glycogen fairly rapidly recycles ATP, but it is slower than from CP. 3 or fewer seconds. Aerobic Energy System. Non-Oxidative or Anaerobic Energy System Instead, the cells where the ATP is produced require glucose (carbohydrates that have been broken down) as the fuel source. It is the main energy system for … The non-oxidative energy sources are glucose and glycogen, which are broken down in the process of glycolysis and glycogenolysis respectively. Non-Oxidative or Anaerobic Energy System. 10–120 seconds. When needed, this energy system provides enough ATP to sustain a short- duration, explosive activity, approximately 10–20 seconds or less. In this phase, as the term indicates you are using oxygen to fuel the breakdown of carbohydrates first, free fatty acids second and if the exercise continues long enough -protein. The nonoxidative energy system typically provides energy for a. The non oxidative or anaerobic Energy System is used for high-intensity activities lasting about 10 seconds to 2 minutes. 3. Unlike the other two systems, the aerobic system requires oxygen and takes much longer to overload. Despite the fact that the oxidative pathway is slow, it can produce enough ATP to sustain activity for long periods of time at a sub-maximal intensity. So non-oxidative processes such as ATP-PC (quickly depleted) and non-oxidative glycolysis enter the game. Glycogen is stored in the muscle cells. The main difference between oxidative and nonoxidative deamination is that oxidative deamination is coupled with oxidation whereas nonoxidative deamination does not proceed through oxidation. The reaction is as follows: Glucose → 2 ATP+2 Lactate. If your body’s energy requirements require effort for over 2 minutes, your body must add oxygen to the mix. Oxidative and nonoxidative deamination are two types of deamination … Training this energy system is great for fat loss, muscle building, and improving overall body composition. Answer: b Page: 64 Topic area: Basic Physiology of Cardiorespiratory Endurance Exercise Bloom’s Taxonomy: Knowledge 21. b. True. So oxidative processes (using fat mainly I guess) are running at 100% (VO2max) but are not sufficient to produce ATP quickly enough (the ATP production rate is not enough to compensate ATP use rate). False. d. 5–60 minutes. One of the interesting things about the oxidative system is that it actually powers itself through the motion of … As the name implies, the non-oxidative energy system does not require oxygen to generate ATP. Furthermore, coenzymes involve in oxidative deamination while oxidizing agents do not involve in nonoxidative deamination. b.
