Document Summary
Edkp395: bioenergetics = convert foods into energy (atp) through chemical pathways/metabolic pathways i. Allows for lifting weights, jumping, etc: many of the precursors come from carbohydrates, the energy for muscular contraction comes from atp; It is the immediate and most important source of energy for muscular contraction. Atp is formed by combining adenine diphosphate (adp) and inorganic phosphate (pi), which requires a rather large amount of energy. Atp formation is a endergonic reaction (adp + pi atp) Atp degradation is an exergonic reaction (atp adp + pi + energy). This regulation is done by the 3 mechanisms mentioned above: mechanism 1: used during very heavy exercise during the rest to exercise transition. This supply is very immediate: mechanism 2: glycolysis does not depend on oxygen. It has a by-product of glycogen: mechanism 3: does not support high power. We want it to work right away when doing exercise the majority of energy is produced through this process.
