GTP (Guanosine Triphosphate)
Guanosine triphosphate (GTP) is a molecule that provides energy for various biological processes in cells, similar to how gasoline powers a car. It consists of the base guanine attached to a sugar (ribose) and three phosphate groups. When GTP releases one of its phosphate groups, it releases energy that fuels activities like protein synthesis, cell signaling, and energy transfer. GTP also acts as a molecular switch, turning certain cellular functions on or off depending on its state, making it essential for normal cell operation and communication.
