Glukos, commonly known as glucose, is a simple sugar that serves as a primary source of energy for the body's cells. It is a type of carbohydrate and is found in many foods, especially fruits and honey. When consumed, glucose is absorbed into the bloodstream, where it can be used immediately for energy or stored in the liver and muscles for later use. In the body, glucose levels are regulated by hormones, primarily insulin and glucagon. Insulin, produced by the pancreas, helps cells take in glucose, lowering blood sugar levels. Conversely, glucagon raises blood sugar levels by signaling the liver to release stored glucose when needed.
