What would happen if the skeletal muscle voltage sensor failed to change from its activated state to its inactivated state following membrane depolarisation?
A) the Ca2+ release channel would not activate
B) released Ca2+ will not be enough to activate force
production
C) Ca2+ release from sarcoplasmic reticulum would be
prolonged
D) there would be no Ca2+ release
E) the surface membrane would not repolarise

Skeletal muscle Ob. smooth muscle Oc. myosin light chain phosphataso Od. A and B QUESTION 9 Action potential leads to activation of neurotransmitter in muscle answer true or false a true b. false c. not sure od silly...
Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles? A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size is approximately equivalent, the ratio of red...
causes the sarcoplasmic retieatum of skeletal musele cells to release calcium onto the sarcomere: what he movement of tropomyosin off of the binding site of actin the binding of acetyleholine with its receptor the binding of caleium with troponin he movement of the action potential down the T-tubal the binding of ATP to the Ca-ATPase on the sarcoplasmic reticulum "Rigor Mortis" is caused b a. the inability of the myosin head to detach from actin b. a lack of calcium...
Please help me with several of these questions, thank you very much. 1. During the propagation of an action potential along the axon of a neuron, what is happening at the leading edge (the front) of the region of depolarization as it moves down the axon? a. Ligand-gated Na+channels are opening. b. Voltage-gated Na+channels are opening. c. Ligand-gated K+channels are opening. d. Voltage-gated Na+channels have become inactive and refractory. e. Voltage-gated Na+channels are closing. 2. During transcellular transport of glucose...
