Glucose is a ubiquitous fuel in biology. It is used as an energy source in most organisms, from bacteria to humans. Use of glucose may be by either aerobic or anaerobic respiration (fermentation). Carbohydrates are the human body's key source of energy, through aerobic respiration, providing approximately 4 kilocalories (17 kilojoules) of food energy per gram. Breakdown of carbohydrates (e.g. starch) yields mono- and disaccharides, most of which is glucose. Through glycolysis and later in the reactions of the Citric acid cycle (TCAC), glucose is oxidized to eventually form CO2 and water, yielding energy, mostly in the form of ATP. The insulin reaction, and other mechanisms, regulate the concentration of glucose in the blood. A high fasting blood sugar level is an indication of prediabetic and diabetic conditions.

Glucose is broken down into the energy units that every cell uses. glucose comes from complex carbohydrates (whole grains, fruits, veggies), but needs to be used in conjunction with proteins (which get broken down into amino acids, then rebuild into protein) for use in the muscles. excessive amounts of carbohydrates are stored as fat.

a concentrated form of energy that can either be used immediately or stored for later use. if you dont use a lot of energy, the excess of glucose will eventually become stores of fat.
