- While the sarcoplasmic reticulum of muscle was first described by nineteenth-century microscopists, its true significance was not ap-preciated until its intricate structure was revealed much later by the electron microscope. What could you tell a nineteenth-century microscopist to enlighten him or her about the structure of the sarcoplasmic reticulum and its role in the coupling of excitation and contraction?Why is it that intermediate filaments have iden-tical ends and lack polarity, whereas actin filaments andmicrotubules have two distinct ends with a defined polar-ity?What is a sarcomere? Illustrate how Z disks, actinmyofilaments, myosin filaments, the M line, and titin form asarcomere. Describe how this arrangement produces theA band, the I band, and the H zone. Label these areas onyour illustration.
- explain why a cell has an electrical charge differenceacross its plasma membrane and, in general terms, howthis relates to muscle contraction.Thick and thin myofilaments have different properties. For each phrase below, indicate whether the filament described is thick or thin (write thick or thin in the blanks).__(1) contains myosin heads__(2) contains actin__(3) does not lie in the H zone__(4) contains myosin__(5) attaches to a Z disc__(6) does not lie in the I bandLight less dense area of sarcomere that contains reminder of thin filaments but no thick filaments is called
- Define collagen fibersDisorders of collagen are characterized by deterioration of connective tissues. Why would such diseases produce widely varying symptoms?Shortly after a person dies, Ca2+diffuses out of the saroplasmic reticulum and the body becomes very still and rigid, a phenomenoncalled rigor mortis (rig′er mōr′tis). Given ATP’s role in myosin head movement, propose an explanation for rigor mortis.
- Contrast the structural and physiological differencesbetween slow-twitch and fast-twitch muscle fibers.Cofilin preferentially binds to older actin filamentsand promotes their disassembly. How does cofilin distin-guish old filaments from new ones?Combining your knowledge of rates of diffusion with yourknowledge of muscle physiology, explain why it is advantageousfor oxidative muscle fibers (which depend on aerobic metabolismto generate ATP) to have smaller diameters than glycolyticmuscle fibers have.
