'''Nutrient sensing''' is a [[cell (biology)|cell]]'s ability to recognize and respond to fuel substrates such as [[glucose]]. Each type of fuel used by the cell requires an alternate pathway of utilization and [[accessory molecule]]s such as [[enzyme]]s and [[Cofactor (biochemistry)|cofactor]]s. In order to conserve resources a cell will only produce molecules that it needs at the time.  The level and type of fuel that is available to a cell will determine the type of [[enzymes]] it needs to express from its [[genome]] for utilization. [[Receptor (biochemistry)|Receptors]] on the [[cell membrane|cell membrane's]] surface designed to be activated in the presence of specific fuel molecules communicate to the [[cell nucleus]] via a means of [[cascading interactions]]. [[Nutrient receptor]]s are receptors that are primarily designed to perform the function of nutrient sensing, whereas other receptors (e.g. [[insulin receptor]]s, [[leptin receptor]]s) are extensively multifunctional and perform many functions besides nutrient sensing.<ref>{{Cite journal |last=A.
