This is a slower process than pumping ions from the cytoplasm. muscle contribute to energy metabolism all of the above d) a) cardiac, acetyl, troponin, potassium b) skeletal, acetyl, tropomyosin, c) smooth, acetyl, tropomyosin, d) smooth, phosphate, myosin, calcium e) Acetylcholine calcium a) stimulates cardiac muscle to b) increases the force of skeletal c) is hydrolyzed by acetylcholine d) is associated with the sympathetic e) skeletal, phosphate, myosin, calcium contract Waves of contraction are coordinated using located inof muscle contractions muscle esterase a) branch of the nervous systenm all of the above channels, focal contacts, smooth b) gap junctions, intercalated discs, e) cardiac c) channels, intercalated discs, d) gap junctions, focal contacts, e) channels, focal contacts, skeletal Focal densities are most similar to cardiac a) gap junctions b) z lines/disks c) receptors d) channels e) microfilaments smooth The correct sequence of events is The strength of a skeletal muscle contraction varies depending on myosin binds ATP, then binds actin. then hydrolyzes ATP, then releases ADP, then releases actin myosin binds actin, then releases actin, then binds ATDP for ATPP, then hydrolyzes ATP and releases ADP a) b) a) b) c) effects of more than one neurotransmitter effects of stimulating more than one site per cell effects of different motor units the amount of carbon dioxide in the environment none of the above c myosin binds actin, then binds ADP, then exchanges ATP for ADP ,then releases actin actin binds ATP, then binds myosin, d) d) e) then hydrolyzes ATP, then releases ADP myosin bound to ADP binds actin Areas calle dare associated with muscle e) transport ofons in myosin exchanges ADP for ATP, myosin releases actin, myosin hydrolyzes ATP a) lipid rafts, sodium, cardiac b) desmosomes, sodium, skeletal c) caveolae, calcium, smooth d) desmosomes, calcium, skeletalExplanation / Answer
Varicosities associated with muscle-b) contain neurotransmitter. All the other options are incorrect because they are not located inside the cells,they are located on the adjacent nerve fibers. The nerve fibers which contain neurotransmitters essentially passes close to the smooth muscle cells. They don't have any role to do with energy metabolism,they are required for backward flow of blood from muscles to heart.
