An enzyme known as acetylcholinesterase is present in the synaptic cleft. What is its role? to break down acetylcholine The sliding filament model of

During muscle contraction, myosin cross bridges attach to which active sites?. Action potential propagation in a skeletal muscle fiber ceases when acetylcholine is removed from the synaptic cleft.. The calcium that initiates skeletal muscle contraction is released from what structure(s)?. In muscle fibers, which regulatory protein blocks the attachment of myosin heads to actin?. How do calcium ions initiate contraction in skeletal muscle fibers?. motor neuron action potential, neurotransmitter release, muscle cell action potential, release of calcium ions from SR, ATP-driven power stroke, sliding of myofilaments. If a muscle fiber were to suddenly and permanently stop producing ATP the fiber would no longer be able to actively transport calcium out of the cytoplasm (sarcoplasm) and the intracellular calcium concentration would rise.. Excitation of the sarcolemma is coupled or linked to the contraction of a skeletal muscle fiber.. The opening of these ACh receptors depolarizes the muscle fiber, which leads to the generation of a muscle action potential.. the loss of ability to contract the muscle Without acetylcholine, the muscle would not be able to contract or even maintain tone

B) In contrast to skeletal muscle, smooth muscle can be stimulated to contract w/o the generation of an action potential.. The delayed onset and prolonged duration of smooth muscle contraction, as well as the greater force generated by smooth muscle compared with skeletal muscle, are all consequences of which of the following?. The delay between the termination of the transient depolarization of the muscle membrane and the onset of muscle contraction observed in both muscles A and B reflects the time necessary for which of the following events to occur?. Choice A: Both actin and myosin are important components of the smooth muscle contractile apparatus much like that of skeletal muscle and cardiac muscle, but these do not play a role in calcium sensitivity.. of muscle contraction will increase the load that a muscle can lift within the limits of the muscle, but will not affect the velocity of contraction.. Choices B, C, and E: Muscle hypertrophy, increasing muscle mass, and recruiting additional motor units will increase the maximum load that a muscle can lift, but these will not affect the maximum velocity of contraction.. This increase in passive tension increases the muscle length beyond its ideal length, which in turn leads to a decrease in the maximal active tension that can be generated by the muscle.
