B) oxygen debts are common.C) most of the muscleʹsenergy is produced inmitochondria. D) fatigue occurs in a fewminutes. E) oxygen is not required.CMuscular force can beadjusted to match differentloads by The type of muscle fiber thatis most resistant to fatigue isthe ________ fiber. B
Fast fibers EDuring the recovery periodthe bodyʹs need for oxygen isincreased because A) muscle cells are producingenergy anaerobically. B) the individual is panting. C) additional oxygen isrequired to restore energyreserves consumed duringexercise. D) the liver requires moreoxygen to produce lacticacid. E) the muscles are notproducing ATP.CDuring the Cori cycle, in theliver During the recovery periodfollowing exercise, all of thefollowing are true, except
After heavy exercise, if energyreserves in a muscle aredepleted, ________ occurs. C) treppe D) tetanus E) atrophyby the muscle. B) 80 percent of the energyrequired by the muscle. C) more than half of theenergy required by themuscle. D) only about one-third of theenergy required by themuscle. E) only about 10 percent ofthe energy required by themuscle.DAt peak levels of muscleexertion the mitochondria cansupply During anaerobic glycolysis Creatine phosphate A) is produced by the processof anaerobic respiration. B) can replace ATP in bindingto myosin molecules duringcontraction. C) acts as an energy reservein muscle tissue. D) is only formed duringstrenuous exercise. E) cannot transfer itsphosphate group to ADP.C
A resting muscle generatesmost of its ATP by The type of contraction inwhich the muscle fibers donot shorten is called The increase in muscletension that is produced byincreasing the number ofactive motor units is called
