can someone help me for this biomechanics assignment

1.) Describe the mechanical action of the actin, myosin, and titin in concentric

contractions, eccentric contractions, isometric contractions, give the amount of force

generated and ATP utilized.

2.) Draw and explain the force-velocity curve. Include an explanation of how the force

per actin-myosin bond affects the force-velocity curve.

3.) How many myosin motors are attached at each velocity?

4.) What role does the force generated from an individual actin myosin crossbridge and titin play in the concentric, isometric and eccentric force – velocity relationship?
