a. Diagram a sarcomere (either by hand/drawing or in a graphicsprogram if you prefer; use the figures from the reading and videosto guide you but don’t turn in a professionally constructeddiagram; generate something on your own). Label key features,including at least: actin, myosin; transverse tubules; sarcoplasmicreticulum; Z-line. (this diagram need not be a perfectrepresentation or of artistic quality – just outline yourthinking)
b. Describe the function of each of the following components(i.e. what is their role in muscle contraction?):
- 1) actin
- 2) actin active site
- 3) myosin & myosin head
- 4) sarcoplasmic reticulum
- 5) transverse (T) tubule
- 6) calcium ions.
c. What process limits the speed at which a muscle can relax aftercontraction?
