- 1Fats can only be used if... (1)Oxygen is present (1), fat can only be used in an aerobic energy system (2)
- 2Explain glycolysis (6)Carbs/glucose/glycogen (1), broken down into pyruvic acid (2), 2 ATP produced (3), krebs cycle (4), fats/triglycerides/glycerol/fatty acids (5), beta oxidation (6), oxidation of acetyl co-enzyme A/production of co2 (7), electron transport chain (8), water formed (8), large quantities of ATP produced/34 ATP (9)
- 3What is beta oxidation? (1)When fatty acids are turned into acetylcoenzyme a (1) in the sarcoplasm (2)
- 4What products does the krebs cycle produce? (3)co2 (1), atp (2), hydrogen (3)
- 5What happens if proteins are used for energy? (2)contains nitrogen (1), it can cause ketoacidosis (2)
- 6How many seconds worth of PC do you have, and how long does it take to recharge? (2)8 seconds (1), 3 minutes (2)
- 7What is the PC/ATP coupled reactions? (2)PC --> C + P (energy for muscles) (1), ATP <-- ADP + P (energy from energy systems) (2)
- 8From each PC molecule we can make.....atp? (1)one (1)
- 9What sports is the PC system good for? (3)short sprint (1), long jump (2), weightlifting (3), discus (4)
- 10When we cannot get oxygen to the ETC, what happens to the hydrogen? (1)Binds with the pyruvic acid to create lactic acid (1), this causes fatigue (2)
- 11What is fatigue? (1)the inability to perform due to depleted energy systems and a breakdown in homeostasis (1)
