What is cross bridge cycling?
when the Thick filaments pull the thin filaments toward the center of the sarcomere
When an object moves in a circle and acts to accelerate the object toward the center of the circle is what?
Centripetal Force is the correct answer
When an object moves in circular path it accelerates towards the center of the circle as a result of?
when an object moved in a circular path it accelerates toward the center of the circle as a result of
What does the term centripetal mean?
It means 'toward the center'.
Where do winds spiral toward the center of a cyclone?
the middle

What happens to a sarcomere when muscle length changes?
1. Arrangement of thick and thin filaments: In each sarcomere two sets of actin filaments extend partway toward the center. The myosin filaments are arranged such that they partially overlap the actin filaments. Myosin heads on each side point away from the center of the sarcomere.2. During contraction, the interaction of myosin heads with the actin filaments pulls the thin filaments toward the center of the sarcomere. The actin and myosin filaments slide past each other.3. Cross-bridges = attachement betwn myosin heads and binding sites on actin filaments.4. When a muscle cell is stimulated, myosin heads are energized by ATP. They attach to adjacent actin filaments, and tilt in a short "power stroke" toward the center of the sarcomere. Each power sroke requires an ATP. With many power strokes in rapid succession, the actin filaments are made to slide past the myosin filaments.
When an object moves in a circular path it accelerates toward the center of the circle as a result of?
When an object moves in a circular path, it accelerates toward the center of the circle due to the centripetal acceleration. This acceleration is necessary to keep the object moving in a curved path rather than in a straight line.
What are the 3 sections along the length of sarcomere?
The three sections along the length of a sarcomere are the A band, the I band, and the H zone. The A band is the dark region in the center of the sarcomere that contains both thick and thin filaments, while the I band is the light region at the ends of the sarcomere that contains thin filaments only. The H zone is the region in the center of the sarcomere where only thick filaments are present.
Which Muscle movement in myosin heads of the thick filaments pull on the thin filaments causing the thin filaments to slide toward the center of the sarcomere?
Flexing of the cross bridge (power stroke)
What is the protein filament that slides inward toward the middle of a sarcomere during a muscle contraction?
Actin
When an object moves in a circle and acts to accelerate the object toward the center of the circle is what?
Centripetal Force is the correct answer
When a muscle is relaxed are there only thin filaments in the center of the sarcomere?
Yep, you got it.
When an object moves in a circle blanke acts to accelerate the object toward the center of that circle is known as what?
Centripetal Force is the answer :)
How does the sun and earth move?
They move because they are both gravitationally bound. The Sun is bound to the Milky Way Galaxy and the Earth is bound to the Sun. Another way to put it is that they revolve around each others common center of gravity. What this mean is that, in the case of the Earth, it is falling toward the Sun's center of gravity but for every foot the Earth moves toward the Sun's center, the Sun moves a foot out of the way. The Sun is moving because it is falling toward the center of our galaxy. Again, it would make it to the center of our galaxy but for one reason. Our galaxy is moving toward the center of the Virgo Super Cluster.
