# Activity 1: Essay **Direction:** Answer the following question. Write your answer in the notebook. 1. Do you think your body is able to use all the glucose you have consumed in your meal? How much is the sugar content in your average meal? # II. WHAT YOU NEED TO KNOW ## Cellular Respiration Cellular Respiration is the process that breaks down food molecules, usually in the form of glucose, to turn into carbon dioxide and water. The chemical equation for cellular respiration is $C_6H_{12}O_6 + 6O_2 \rightarrow 6H_2O + 6CO_2$. This is the reverse chemical reaction of photosynthesis. However, it undergoes a different process. In cellular respiration, ATP is produced to be used in all cellular processes that require energy. This chemical equation of cellular respiration is also a redox reaction. Because glucose has lost an electron, it is.
