KIN 3339AExercise Nutrition thLecture 8Monday September 26 2011 Fuels Available to MuscleSlide 27NOT asked to reproduce glycolysis or oxidative phosphorylation diagrams o Know substrates and endproducts thoughThese are processes that help us get the energy for whatever it is that we want to doFuels that muscles use o ATP We have this in our bodies right nowWe made it from food that we ate this morning or last nightStored and readily available y If someone were to yell fire o We would use this stored ATP as energy to get out of the buildingAmount of ATP stored is very smally So if we were to exercise at our topmost level of intensity the ATP would only be our fuel for the first 12 seconds y The process we use to recreate ATP is very important because this is the chemical compound we use to derive energy o PCrTogether with ATP the combination provides about 35 seconds worth of energy that can be used when we are exercising very intenselyHowever in order to use PCr you need to convert it into ATPSee chemical reactions y ATPase reaction in the muscle o ATP broken down via ATPase to ADP inorganic phosphate and energyNow the chemical energy that was holding the ATP molecule together has been released and is available for muscle contraction y Cr Kinase reactiono ADP is combined with PCr and some hydrogen irons to produce more ATP o Then we take that endproduct of ATP and we can break it down again through the ATPase reaction to get more ADP which can serve as the substrate for the Cr Kinase reaction which makes more ATPit is a constant cycle of energy generation
