X it by the molar mass of tungsten
If you think of it endothermic is when there is energy needed for the reaction to occur and exothermic is when the reaction releases energy
Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid.
