Stored chemical energy that links energy yielding & energy requiring functions within a cell

lasts about 15-30 seconds

oxygen is not utilized but is present in order to regenerate ATP, by product is lactic acid, lasts about 2-3 minutes

3 Components, all require oxygen to be present & is utilized

Glycolysis, Krebs, ETS/OP

process by which cells transfer energy from food to ATP, relies on oxygen

not requiring or utilizing oxygen

requires, utilizes oxygen

stored glycogen is broken down to provide glucose

responsible for the initial breakdown of glucose. begins with glucose or glycogens ends with pyruvate or lactate

creation of glucose in liver from non carbohydrate sources, particularly glycerol, lactate or pyruvate

utilized when resting muscles have stable levels of glucose

when insulin and glucose levels are high

breaks off successive pairs of carbon atoms from FFA which are then used to form Acetyl CoA

ph level decrease, glucose level decrease, temperature increase gluconeogenesis will begin

Necessary to maintain blood glucose levels during exercise
