According to the sliding filament theory of muscle contraction:

muscle fibers contain thin myofilaments made up of a protein called myosin.
b)
muscle fibers contain thick myofilaments made up of a protein called actin.
c)
Thin and thick myofilaments bind to cause muscle contraction.
d)
All of the above.
44.
When an organism dies, its muscles may remain in a contracted state called RIGOR for a period of time. Which of the following is most directly responsible for this phenomenon?
a)
no energy for the synthesis of actin and myosin
b)
no ATP to detach the cross-bridges between the thin and thick myofilaments
c)
no calcium to bind to the myofilaments
d)
no lactic acid present in the muscle
45.
TURN ON CAPS LOCK! _______________________attach muscles to bone, ______________________attach bones to bones
(a)
46.
TURN ON CAPS LOCK! During muscle contraction (a) ions must be present to start the binding of the actin and myosin
47.
TURN ON CAPS LOCK! (a) is one type of protein that prevents the attachment of actin and myosin
48.
TURN ON CAPS LOCK! Thin myofilaments are called ________________and thick myofilaments are called _______________.
(a)
49.
TRUE or FALSE: This is the correct order of events for muscle contraction: Thin and thick myofilaments attach by means of a cross-bridge and ATP “readies” myosin for the power stroke movement. A nerve impulse reaches the muscle, triggering the release of calcium ions into the cytoplasm of the muscle cell. ATP “breaks” the myofilament bridge, relaxation occurs, and Ions are pumped back into the sarcoplasmic reticulum. Released ions cause the troponin-tropomyosin complex to roll away and prepares actin to bind to myosin
a)
True
b)
False
100 %
