Document Summary
3 energy systems through which cells generate atp: atp-pcr = anaerobic, glycolytic system (glycolysis) = anaerobic or aerobic (different end products, oxidative system (oxidative phosphorylation/ oxphos)= aerobic, consists of etc and chemiosmosis. Anaerobic exercise comprises brief, strength-based activities, such as sprinting or bodybuilding. Aerobic exercise is centered around endurance activities, such as marathon running or long-distance cycling. However, the early stage of all exercise is anaerobic. Creatine kinase = enzyme that catalyzes the reaction and releases energy from pcr: increase adp+ pi = increase enzyme activity, increase atp/ decrease adp+pi = decreased/ inhibited enzyme activity. For example: at the start of intense ex, atp is broken down quickly for immediate energy, giving adp and pi, as exercise progresses and atp is generated by the other two systems (glycolytic and oxphos), Increased adp + pi conc = increased creatine kinase activity to regenerate more atp creatine kinase activity decreases/ is inhibited.
