A) Describe the difference between strength and power during a squat. Provide a quantitative example that illustrates the difference.
B) During a squat, the weight you have on your shoulders has a certain amount of gravitational potential energy. As you squat down and come to a stop at the bottom of the squat, some of that energy is lost. Where does it go?
We move a lot and do not even realize how intricate these movements may be from gross motor to fine motor manipulations. Briefly explain the steps involved in a single muscle contraction beginning at the neuromuscular junction through one complete contraction and relaxation for the sliding filament theory. Don’t forget to include all the major proteins (actin, myosin, troponin and tropomyosin) involved as well as calcium and ATP.
The sliding filament model depicts how myosin motors attached to actin lead to muscle contraction. This process proceeds in a precise series of events. Indicate which of the following shows the correct order of steps in the sliding filament model.
Group of answer choices
Myosin binds ATP; myosin tightly binds actin; power stroke; myosin releases actin
Myosin binds GTP; myosin releases actin; power stroke; myosin tightly binds actin
Actin binds ATP; power stroke; myosin tightly binds actin; actin releases ADP
Actin binds ADP; myosin releases actin; power stroke; actin releases ADP

- 15) what role does calcium play in muscle contraction? a) calcium is not involved in skeletal muscle contraction b) it binds to tropomyosin and moves Tripp in away from the myosin binding sit on the actin molecules c) it's binds to Troponin and moves tropomyosin away from the actin binding sit on the myosin molecules d) it binds to troponin and moves tropomyosin away from the myosin binding site on the actin molearrow_forwardWhat do you mean by myofibrils?arrow_forward2) Paula is a scientist who is developing a drug called Fremtol that will be used to treat muscle spasms. This drug acts on specific skeletal muscles to (1) block the release of Ca2+ ions from the sarcoplasmic reticulum, (2) inhibit the pivoting ability of the myosin heads of the thick filaments, and (3) block the production of ATP by the mitochondria in skeletal muscles. By using this drug, contraction of certain skeletal muscle fibers is reduced, which keeps those muscles from producing spasms. In the above scenario, Fremtol’s effect of blocking the release of Ca2+ ions from the sarcoplasmic reticulum would most directly prevent which the following? a. activation of tropomyosin b. activation of troponin c. activation of actin d. All of the above e. None of the abovearrow_forward
