The ion necessary to link myosin to actin for muscule contraction is:
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
Myosin and actin make up
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
What happens when the thin filaments in a muscle fiber slide over the thick filaments?
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
Muscle tone refers to:
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
Where is the protein called actin loacted in the body?
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
Rigor Mortis is a stiffening of the muscles after death due to:
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
Regular exercise does the following:
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
In addition to myosin, what other protein is involved in skeletal muscle contraction?
myofibrils
a state of sustained, partial contraction of muscles that is necessary to maintain posture
thin filaments
a muscle contracts
calcium
actin
the Calcium levels are higher than the ATP levels which keeps the myosin binded to the actin
increases the number of myofibrils which increases muscle size and strength
