using oxygen to breakdown glucose ) into CO 2 producing ATP, yields 36 ATP/glucose

breaking down glucose without oxygen to produce ATP, yields 2 ATP/glucose

transfers Pi from creatine phosphate to ADP

which is not a cause of muscle fatigue

lactic acid lowering pH and inhibiting enzymes

slow twitch filers are:

endurance fibers; abundant mitochondria, myoglobin, and blood vessels

quick, strong contractions; rich in creatine and glycogen, SR releases Ca 2+ quickly, few mitochondria and blood vessels, little myoglobin

fast twitch filers are:

quick, strong contractions; rich in creatine and glycogen, SR releases Ca 2+ quickly, few mitochondria and blood vessels, little myoglobin

endurance fibers; abundant mitochondria, myoglobin, and blood vessels

tetani secretes a toxin that blocks an inhibitory neurotransmitter called glycine resulting in overstimulation of muscles

3-4 hours after death SR deteriorates releasing Ca 2+ stimulating contraction

muscle spasms triggered by heavy exercise, cold, dehydration, electrolyte loss, low blood glucose, or lack of blood supply

hereditary disease where muscles degenerate and are replaced by fat and fibrous tissue

autoimmune disease in which antibodies attack neuromuscular junctions and bind Ach receptors together (muscles become less and less responsive to Achieving)
