Web18 de dez. de 2016 · Inhibitors that are specific to different enzymes within a signal transduction pathway can drastically change the cellular response that gets initiated. … WebTHC’s chemical structure is similar to the brain chemical anandamide. Similarity in structure allows the body to recognize THC and to alter normal brain communication. Endogenous cannabinoids such as anandamide (see figure) function as neurotransmitters because they send chemical messages between nerve cells ( neurons ) throughout the …
Web1 de abr. de 1997 · Plants use many different chemicals to send signals. Auxins, cytokinins, abscisic acid, gibberellic acid, and ethylene are “classical” phytohormones; however, a number of very recently discovered phytohormones include brassinolide ( 3 ); systemin, a peptide hormone; methyl jasmonate; and salicyclic acid. The ethylene signal transduction ... WebThe primary target for regulation of a biochemical pathway is often the enzyme that catalyzes the pathway’s first committed step (that is, the first step that is not readily reversible). The concept of a committed step can get a little complicated when there are many intersecting metabolic pathways, as in cellular respiration, but this is still a useful …
