Glycolysis simply means the breakdown (lysis) of glucose and consists of a series of chemical reactions that are controlled by enzymes.
Steps of the anaerobic glycolytic system: 1  Initially stored glycogen is converted to glucose. 2  Glucose is then broken down by a series of enzymes. 3  2 ATP are used to fuel glycolysis and 4 are created so the body gains 2 ATP to use for muscular contraction. Think of the anaerobic glycolytic system as the V6 car engine opposed to the V8 of the ATP-PC system, or the huge diesel engine of the aerobic system. The anaerobic glycolytic system produces a lot of power, but not quite as much or as quickly as the ATP-PC system. Because glycolysis relies on energy converted from carbohydrate (glucose) into ATP, your glycolytic system is slightly less responsive than your ATP-CP system. But it can still provide as much as half the energy you need in the first few seconds of intense exercise. (See “An Energy Systems Timeline,” below.).  The anaerobic glycolysis (lactic acid) system is dominant from about 10–30 seconds during a maximal effort. It replenishes very quickly over this period and produces 2 ATP molecules per glucose molecule, or about 5% of glucose's energy potential (38 ATP molecules). Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes. Glycolysis simply means the breakdown (lysis) of glucose and consists of a series of chemical reactions that are controlled by enzymes. Think of the anaerobic glycolytic system as the V6 car engine opposed to the V8 of the ATP-PC system, or the huge diesel engine of the aerobic system. The anaerobic glycolytic system produces a lot of power, but not quite as much or as quickly as the ATP-PC system. However it has larger fuel supplies (a bigger fuel tank) and doesn’t burn all its fuel as quickly as the ATP-PC system, so it doesn't fatigue as quickly as the ATP-PC system. Steps of aerobic glycolysis: 1  Initially stored glycogen is converted to glucose. 2  Glucose is then broken down by a series of enzymes. 3  2 ATP are used to fuel glycolysis and 4 are created so the body gains 2 ATP to use for muscular contraction. The second and third stages of the aerobic energy system continue the breakdown of glucose that was started by aerobic glycolysis and result in the formation of the by-products carbon dioxide (CO2) and water (H2O), and the synthesis of more ATP. (December 2009). Anaerobic glycolysis is the transformation of glucose to pyruvate when limited amounts of oxygen (O 2) are available. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes. As an intermediate pathway between the phosphagen and aerobic system, anaerobic glycolysis can produce ATP quite rapidly for use during activities requiring large bursts of energy over somewhat longer periods of time (30 seconds to three minutes max, or during endurance activities prior to steady state being achieved).  The Anaerobic Glycolytic System (fast glycolysis). Learn all about the energy system that 'burns' right here. The 'burn' isn't lactic acid by the way. Lactic acid is only produced by cows, so be wary of anyone that tells you your 'burn' is due to a lactic acid build-up. Think of the anaerobic glycolytic system as the V6 car engine opposed to the V8 of the ATP-PC system, or the huge diesel engine of the aerobic system. The anaerobic glycolytic system produces a lot of power, but not quite as much or as quickly as the ATP-PC system. The aerobic system—which includes the Krebs cycle (also called the citric acid cycle or TCA cycle) and the electron transport chain —uses blood glucose, glycogen and fat as fuels to resynthesize ATP in the mitochondria of muscle cells (see the sidebar “Energy System Characteristics”). For every molecule of glucose broken down to pyruvate through glycolysis, two molecules of usable ATP are produced (Brooks et al. 2000). Thus, very little energy is produced through this pathway, but the trade-off is that you get the energy quickly.
