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.
Muscarinic receptors are G-protein linked receptors that are activated by acetylcholine. That makes A) true. Both nicotinic and muscarinic ACh receptors are located on the postganglionic cells in both the sympathetic and parasympathetic nervous systems.However, neither ACh receptor is located on the preganglionic cells of either the sympathetic or parasympathetic systems.uscarinic receptors are G-protein linked receptors that are activated by acetylcholine. That makes A) true. Both nicotinic and muscarinic ACh receptors are located on the postganglionic cells in both the sympathetic and parasympathetic nervous systems.
