Answer to Question #143368 in General Chemistry for paiwand salih

Question

How the change of shape can affect the signal transduction? Consider the addition of long alkyl chain.

Answer 1

Signal transduction pathway involves the binding of extracellular signaling molecules and ligands to receptors located on the cell surface or inside the cell that trigger events inside the cell, to invoke a response. The response can then alter the cell's metabolism, shape, and gene expression.

signal transduction pathways is turned off when the result of decrease in the cellular response to a second messenger. The most obvious method for turning off a signal is the dissociation of the ligand from the receptor. Ligand dissociation can be induced (a cellular process),or can occur due to a decrease in the circulating ligand concentration
