Why lactate is produced Study Guide 1. List the four steps that answer the question: Where does energy come from? Energy used by our bodies comes originally from the sun in the form of heat and light. Heat and light are converted into chemical energy in the form of food. Inside our bodies the energy from food is used to produce a compound called ATP. ATP is the basic fuel that powers all of our bodily functions including the contraction of our muscles. 2. At what point is the aerobic system working at maximal capacity (VO2max) As intensity increases the aerobic system responds by using more O2. At the point where we can’t use O2 any faster the aerobic system is working at maximum capacity. 3. Why are the ATP-CP and lactic acid energy systems anaerobic? They are anaerobic because they function without O2 and are important for burst of high intensity effort for short periods of time. 4. The alactic and lactic acid system are collectively referred to as ______? Anaerobic glycolysis 5. Under what conditions is pyruvate converted into lactate? When the aerobic system cannot keep up with the athlete’s energy demands pyruvate will be converted to lactate. 6. What enzyme is required to convert pyruvate to lactate + H+? Lactate dehydrogenase 7. Why are enzymes considered to be catalysts? Enzymes increase the rate of chemical reactions. 8. You should know how enzymes work – no excuses! Review highlight in notes PAGE 2, 3 9. Understand how pathways work – again no excuses for not knowing this. It should be review for you. Review highlight in notes PAGE 3
