Lecture 11: Energy metabolism.  Levitsky’s rap Why do we eat sugar? o Sugar is a surrogate for energy Energy metabolism o Metabolism is the process of converting energy form carbon hydrogen bonds to  phosphate bonds.  o ATP (adenosine triphosphate) o When muscle or gland wants to use energy, it cuts ATP o Goes into work and it releases the phosphate which makes it into ADP +P  (Adenosine Diphosphate.) use to work o When you eat food, this process reverses and the metabolism puts phosphate  back into ADP. Making ATP o Cell (for energy metabolism) Cytoplasm (most of the cell) We can actually make ATP in the cytoplasm without oxygen. (quick) Mitochondria: ultimately produce most of the energy that we need by  producing ATP.  When the glucose comes in the cell goes into glycolysis. This process  splits glucose into pyruvic acid (half the chain). While breaking +4 ATP
