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.
The enzyme acetylcholinesterase (ACh) breaks down the acetycholine in the neuromuscular junction. You can prevent nerve transmission by 1) preventing the release of ACh, or 2) preventing the released ACh from working on the next (postsynaptic) target.his is in contrast to the succinylcholine, which binds to receptor and prevents the muscle from firing, due to hyperpolarization-so even if the ACh binds, it can't fire the muscle. And as for the muscle contraction: This explains it beautifully.
