PE 205 Show What Ya Know Muscle Tissue Name 1 The myosin binding site is on which protein a titin b troponin c tropomyosin d actin 2 When an ATP molecule binds to the myosin head a b c d the myosin pulls the actin toward the bare zone the myosin head cocks into the ready position the myosin head lets go of the actin the actin binding site opens up Mark A if the characteristic applies to a slow oxidative fiber B if it applies to a fast oxidative fiber C if it applies to a fast glycolytic fiber 3 contains plenty of glycogen 4 small diameter minimal power very fatigue resistant 5 has large powerful fibers 6 contains plenty of mitochondria capillaries and myoglobin 7 well suited for endurance activities 8 Which of these involves an eccentric contraction a you re lifting an object heavier than you re used to b you re lowering yourself from a bar when doing chin ups you re biceps brachii is lengthening while developing tension c you cock your arm behind your head before putting up a free throw d you stretch your hamstrings and calf muscles before running a sprint 9 A muscle with many motor units would be built for a power b good looks c detailed control d stability Mark A if it applies to direct phosphorylation making ATP using creatine phosphate B if it applies to glycolysis C if it applies to aerobic respiration 10 can result in the formation of lactic acid 11 requires oxygen 12 forms a whole bunch of ATP MATCH THESE WITH THE BEST ANSWER 13 isotonic concentric contraction a controls joint motion 14 isotonic eccentric contraction b results in no joint motion 15 isometric contraction c initiates joint motion 16 An athlete is trying to enhance his treppe What s he doing a trash talking his opponent b stretching to avoid injury c warming up his muscle so the chemicals in it work better d performing public service to offset the bad press he s been receiving 17 Length tension relationship refers to the fact that a the longer you and your gender balance remain in a relationship the less tension remains between you b a long skinny muscle biceps brachii develops more tension than a short broad one gluteus maximus c a muscle generates more force on a long bone than on a flat bone d a muscle generates more force when at or slightly longer than its normal resting length GREATER OR LESS MARK WHICH IS GREATER MARK C IF THEY RE THE SAME 18 a percentage of fast glycolytic fibers in the arms of a home run champion b percentage of fast glycolytic fibers in the legs of a marathon runner c they re both the same 19 a number of motor units used when bench pressing 300 b number of motor units used when bench pressing 100 c they re both the same 20 a external passive tension b internal active tension c they re both the same
