Answer:
ATP is the form of energy that your cells require to perform their functions. This form of energy is made in the mitochondria in a process known as cellular respiration.
Step-by-step explanation:
***I'm assuming that this question relates to respiration as it has to do with energy. ATP energy are products of cellular respiration. Along with ATP energy, we also have 2 more products, which is H2O and CO2.
We breathe out carbon dioxide since we don't need CO2 in our bodies and we sweat water by the amount of heat + energy you are using up.
***We need to undergo cellular respiration to obtain energy. To obtain this energy, you need the mitochondria as it is the powerhouse of the cell. The mitochondria creates that energy you need as a living organism.
