Question

7 Which events in daily life cause the formation of CO2?

Answer 1

Breathing out!

Explanation:

Aerobic cellular respiration happens all the time in the human body, and it is the process of cells using organic nutrients, such as glucose, and combine it with oxygen gas to form carbon dioxide and water. The balanced chemical equation for that is:

`C_6H_12O_6(aq)+6O_2(g)->6CO_2(g)+6H_2O(l)`

Note that energy is also produced from the reaction from the breakdown of glucose into `"ATP"`. This generally occurs in three steps, glycolysis, Krebs cycle, and the electron transport chain `("ETP")`.

We released out the waste gases, carbon dioxide in this case, by breathing. Therefore, we can technically say that breathing and respiration are one of the causes of formation of `CO_2`.
