Short Term

 

Definition
  • C-P +ADP -> C ATP (short bursts)
  • Glycolysis- Glycogen -> glucose ->->-> pyrovate-> mitochondria= ALOT of ATP (Moderate)
  • (or) pyrovate-> lactic acid->blood-> liver (peak activity)=90 % glucose goes to lactic acid, 10 to mitochondria
  • for liver to convert back to glucose takes a lot of energy
  • very effecient with enough oxygen (when it goes to mitochondria)
  • limitation of mitochondria= amount of oxygen
Term
Slow Twitch
Definition
  • aerobic
  • more blood supply
  • more # mitochondria
  • more myoglobin= oxygen storage
Term
Fast Twitch
Definition
  • anaerobic
  • less blood supply
  • less # mito
  • more #myofibrils
  • more number of glycogen stores
Term
Muscle Contraction
Definition
  • trigger= calcium
  • calcium comes from SR
  • calcium stimulated by an action potential
  • calcium binds to troponin, troponin moved tropomyosin away from actin head (now exposed)
  • actin binds to myosin
  • power stroke= contraction (ATP is stored in mysoin head)
  • ATP releases myosin head
  • ATP recocks the myosin head
