cell respiration

Cell respiration is the process by which cells generate energy from the food we eat. It mainly involves breaking down glucose, a sugar, with the help of oxygen, producing energy in the form of a molecule called ATP. This process releases carbon dioxide and water as byproducts. Essentially, cell respiration is how our bodies convert food into usable energy to power all bodily functions, from muscle movement to brain activity. It is a vital, continuous process that keeps our cells alive and functioning efficiently.
