Answer:
When Tamara eats a candy bar, her body breaks down the carbohydrates in the candy bar to glucose in a process called glycolysis. The glucose is then transported into her cells, where it undergoes a series of chemical reactions called cellular respiration that result in the production of ATP, a molecule that provides energy to the cells. In short, the chemical reaction that occurs in Tamara's body when she eats a candy bar is cellular respiration, which converts glucose into ATP to provide the energy needed for her cells to function.
