CQ: Although all the anatomical parts of muscle work together to give it it's characteristics, which of the following proteins listed below would be most associated with the characteristics of excitability?
CQ: Put in the correct order
Ach released by the synaptic vesicles crosses synaptic cleft; then acetylcholinesterase breaks down Ach
Calcium ions released from SR and binds with troponin
Myosin heads combine with actin-binding sites
Impulse stops, calcium or ATP depleted, calcium ions return to SR
Calcium binds to troponin, shifting tropomyosin to unblock actin-binding sites
Sodium ions enter the muscle fiber, initiating an action potential that travels down the T-tubules to the Terminal Cisternae
Calcium is actively pumped back to SR
With ATP present, ATPase splits ATP to ADP + P + Energy
Motor nerve impulses (AP) to the neuromuscular junction
Tropomyosin covers binding sites, myosin no longer bound
Sliding action of actin over myosin (Sliding Filament Theory)
