Final answer:
Cellular respiration releases energy stored in chemical bonds of glucose to produce ATP, carbon dioxide, and water. The original atoms in glucose are not converted to energy but rearranged into byproducts, capturing energy in ATP.
Step-by-step explanation:
During the process of cellular respiration, energy that is stored in the chemical bonds of glucose is released. This energy is transferred to ATP (adenosine triphosphate), which is a molecule that provides energy for cells to perform various functions, such as muscle movement. The cell produces carbon dioxide and water as byproducts of this process.
The overall chemical reaction for cellular respiration is C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + Energy (ATP). This series of chemical reactions is divided into three stages: glycolysis, the Krebs cycle, and the electron transport chain, resulting in the generation of ATP.
It's important to remember that the original atoms of carbon, oxygen, and hydrogen from glucose and oxygen are not converted into energy; they simply rearrange into carbon dioxide and water. The energy that was used to hold these molecules together is instead captured in the form of ATP and some energy is released as heat.
