PhosphoRus, Proton Imaging and Amyloid BuRdEn (PREPARE) ON AMYLOID BURDEN AND COGNITION

Normal cells primarily produce energy with the help of the "mitochondria". These "small organs" are also called the "powerhouses of the cell" turn the sugars, fats and proteins that is eaten into forms of chemical energy that the body can use to carry on living. This process is called oxidative phosphorylation. In addition to the help from the mitochondria and oxidative phosphorylation, most cells can produce energy by lactic acid fermentation. This process is less energy efficient but faster and used by the brain, muscle or other organs under specific circumstances and energy demands, even in the presence of abundant oxygen. It is also called aerobic glycolysis. Aerobic glycolysis and oxidative phosphorylation are the two major mechanisms involved in brain energetics.
