Document Summary

Skeletal muscle - causes the demand for energy, dictates change in everything else! We are using oxygen to break down the fuels that our body needs to keep going! Produces: metabolic by-products = carbon dioxide, heat, la etc these get. Lactic acid byproduct: can change the ph which isn"t good for the system! transferred away from skeletal muscle! Supply tissues: fuels to heart and circulation ! Skeletal muscle (conserves own energy so readily available)! Skin (red faces - increased blood ow dissipates heat)! Liver (lactic acid - converts to glucose)! Heart (likes to use lactate as energy)! *** as you train, some muscle bres can use lactate! **review** 3 main sites we need energy for:: sarcoplasmic reticulum (pumps calcium), myosin heads (allows cbs to move), sodium potassium pump! We need to constantly rebuild it ! Fuel > energy > work! bioenergetics: the study of energy transfer via chemical reactions in living tissues!
