In humans, the products of anaerobic respiration are adenosine triphosphate (ATP), carbon dioxide and lactic acid. ATP is the molecule that provides energy to cells.
Two Types of Receptors. There are two types of acetylcholine receptors (AChR) that bind acetylcholine and transmit its signal: muscarinic AChRs and nicotinic AChRs, which are named after the agonists muscarine and nicotine, respectively.he muscarinic AChRs occur primarily in the CNS, and are part of a large family of G-protein-coupled receptors (G proteins), which use an intracellular secondary messenger system involving an increase of intracellular calcium to transmit signals inside cells.
ACh binds to neuronal nicotinic acetylcholine receptors (nAChRs) located on postganglionic neurons. Nicotinic AChRs are the main mediators of ganglionic fast synaptic transmission, and, in this respect, they function as an interface between nervous system and peripheral organs.his article focuses on the role of nicotinic acetycholine receptors (nAChRs) in the control of organ systems innervated by the autonomic nervous system. As the main mediators of fast synaptic transmission in ganglia, nAChRs are key molecules for the processing of neural commands directed to the peripheral organs.
