MUSCLE PHYSIOLOGY TEST QUESTIONS
actin
The head of the myosin molecule binds to __ to form the crossbridge.
tropomyosin
What regulatory molecule on the thin filament covers the myosin head binding site on
actin?
troponin
Which molecule on the thin filament has a binding site for calcium?
ATP
The binding of __ to the myosin head puts the crossbridge in its high energy
conformation.
ATP
__ must bind to the crossbridge for it to disconnect from the actin molecule.
ATP
__ is responsible for moving calcium back in the sarcoplasmic reticulum.
power stroke
What causes the sliding of the thin filament toward the middle of the sarcomere?
True
T or F. The thin filament does NOT shorten during muscle contraction.
depletion of ATP
What is the cause of rigor mortis?
True
T or F. An increase in the strength of the stimulus will cause an increase in tension
development caused by recruitment of more motor units.
temporal summation
When a second stimulus is applied before complete relaxation it is called __ __.
endomysium
Skeletal muscle cells are electrically insulated from each other by __.
positive
If the Na+ or fast Ca+ channels are open, the inside of the cell would become relatively
more __.
sarcoplasmic reticulum
Ca+ is stored where in contractile cells?
the flow of positive Na+ ions
What causes an A.P. in contractile cells?
Na+
The depolarization phase of contractile cells is caused by the opening of __ voltage-
gated channels.
Ca+
The repolarization phase of contractile cells is delayed by the plateau phase. The
opening of __ voltage gated channels is responsible for the plateau phase.
in the high-energy form, w/ ADP and P bound to it
When a muscle cell is relaxed and intracellular ATP levels are normal, a crossbridge will
remain what state?
C
