The parasympathetic division of autonomous nervous system is also known as craniosacral division. The cell bodies of preganglionic neurons of parasympathetic division are located in the lateral gray matter of sacral segments (S2-S4) of spinal cord and in the nuclei of four cranial nerves in the brain stem. These cranial nerves as namely: oculomotor nerve (III), facial nerve (VII), glossopharyngeal nerve (IX), vagus nerve (X).
D. The reaction will release energy the organism can use to do work.
Explanation:
A negative ∆G means that the products have less free energy than their reactants. This energy had to go somewhere, it can't just disappear. That means that 255kJ of energy was released, turning into free energy for the organism to use for work.
Neurotransmitters, such as acetylcholine--the major neurotransmitter found in the human body, act over a short time and they are quickly removed from the synapse by enzymes (i.e. acetylcholinesterase which breaks down acetylcholine to acetyl-CoA and choline).
