KINE 150 Lecture Notes - Lecture 2: Cellular Respiration, Carbohydrate Metabolism, Glycolysis
Document Summary
Coaches and athletes need to understand that there are many factors that contribute to a process called glycolysis which significantly impacts energy production. The lactic energy system produces atp by breaking down glycogen through: anaerobic glycolysis (without oxygen, aerobic glycolysis (with oxygen) - this contributes the glycolytic energy production and hence aerobic fitness levels have a significant role to play. Lactate is always produced as a by-product of carbohydrate metabolism, both aerobically and anaerobically, but lactate only accumulates when the aerobic energy system cannot keep up with the rate at which lactate is being produced. There are four key steps involved in the anaerobic glycolytic system. Steps of the anaerobic glycolytic system: initially, stored glycogen is converted into glucose. Aerobic and anaerobic respiration: the breakdown of glucose to synthesize atp results in the creation of a substance called pyruvate" and hydrogen ions.
