When describing the muscle excitation-coupling sequence, all of the following are true EXCEPT
1. An action potential arrives at the neuromuscular junction and
triggers the release of the neurotransmitter, acetylcholine
2. Ca 2+ binds to troponin causing it to change shape, exposing binding
sites for myosin on the actin filaments
3. ADP binds onto actin allowing it to release the myosin heads ready
for the next action potential to arrive
4. The postsynaptic action potential propagates along the sarcolemma
and down the T-tubules

because it's right I got right in my test

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
