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.
