Document Summary

Electrons are pumped to oxygen and every time they are moved to oxygen they pump and proto, 1 electrons gives you 3 protons. Oxygens pulls the electrons the strongest magnet. The oxidative system involves the breakdown of substrates in the presence of o2. This system yields more atp than the atp-pcr and glycolytic system. Oxidation of cho involves glycolysis (ae), krebs cycle and etc. The result is h20, co2, and 32 atp per glucose mol (1:32): correction for manual page (cid:1005)(cid:1006)(cid:1013): (cid:858)(cid:1007)(cid:1012) atp(cid:859) should read (cid:1007)(cid:1006) (re(cid:272)e(cid:374)t e(cid:448)ide(cid:374)(cid:272)e changes this classic rule) O(cid:454)idatio(cid:374) of fat i(cid:374)(cid:448)ol(cid:448)es (cid:858)(cid:271)eta-oxidatio(cid:374)(cid:859) that pro(cid:448)ides a(cid:272)et(cid:455)l coa: fat: atp depends on the type of fatty acid. The oxidative capacity of the muscle depends on enzyme concentrations (mitochondrial content) which is related to fibre type, and depends on o2 availability. Energy system contributes at the start of high intensity exercise. All 3 systems turn on instantly, some just turn on faster than other.
