ATP - the chemical energy used for most cell processes - energy is released when a phosphate group is removed - ADP is then produced (can be converted back to ATP)
Formation of ATP - ATP comes from the breakdown of food (organic compounds) - your food does not directly contain ATP for your cells
Formation of ATP (cont) - Carbohydrates are the most commonly broken down - glucose is the most common - Lipids produce more ATP than any other - Proteins are rarely broken down
