Phosphorylation
Phosphorylation is a chemical process where a phosphate group (a small molecule made of phosphorus and oxygen) is added to a protein or other organic molecule. This addition changes the molecule's shape or function, often acting like a switch that turns processes on or off in cells. It plays a crucial role in regulating various cellular activities, including metabolism, signal transduction, and cell division. Essentially, phosphorylation is vital for controlling how cells behave and respond to their environment, making it a key player in many biological functions.

Phosphorylation is a chemical process where a phosphate group (a small molecule containing phosphorus and oxygen) is added to another molecule, often a protein. This addition can change the protein's shape and function, influencing various biological activities like metabolism, cell signaling, and gene expression. Think of phosphorylation as a switch that can turn a protein "on" or "off," helping cells respond to changes in their environment. It’s a crucial mechanism in many cellular processes, including the regulation of energy use and communication between cells.
