A is the correct answer!
- water can moderate temperature v. well that's why it's used as a cooling agent
- water expands upon freezing (that's why ice floats on water!)
The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.

<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
