Document Summary

Adipose tissue stores fat, breaks down fuel. Muscle itself don"t need to transport (internal source); readily available. Skin blood flows close to skin to dissipate heat during exercise red face. Liver removes ammonia and lactate (can convert lactate back to glucose) Can move for a short period without oxygen (anaerobic metabolism) Metabolism of muscle helps regulate body temperature. Produce co2, heath, and fuel by-products eg. lactic acid (la + h+, which decreases ph) Heat is the main by product; these are all transported away from muscle. Bicarbonate system helps buffer ph changes in the blood. 3 main sites energy is required for contraction: sr (pumps ca2= back into sr, myosin heads (to detach them, na+/k+ pumps (maintain electrical chemical gradient) Bioenergetics: study of energy transfer via chemical reactions in living tissues. Most prevalent usage during high intensity: carbs. Most prevalent usage during rest: fat (adipose tissue) 4 main forms of energy: heat, chemical, mechanical, electrical.
