Final answer:
Cellular respiration involves the breaking and formation of chemical bonds in the conversion of carbohydrates and oxygen into carbon dioxide, water, and ATP. The energy released from the breaking of these bonds is used to synthesize ATP, which cells use as an energy source. The original matter, such as carbon, oxygen, and hydrogen, remains in the final products of cellular respiration, which are carbon dioxide and water.
Step-by-step explanation:
Cellular respiration is a process in which carbohydrates and oxygen are converted into carbon dioxide, water, and ATP (adenosine triphosphate) through a series of chemical reactions. These reactions involve the breaking and formation of chemical bonds. When the bonds in carbohydrates are broken, energy is released and stored in the form of ATP. This energy is then used by cells to perform various functions.
For example, during glycolysis, the first phase of cellular respiration, glucose (a carbohydrate) is broken down into pyruvate, generating a small amount of ATP. In the subsequent phases, pyruvate is further broken down in the presence of oxygen, releasing more ATP and producing carbon dioxide and water as byproducts.
The breaking and formation of chemical bonds in cellular respiration is essential for the transfer of matter and energy. The bonds in carbohydrates are high in potential energy, and when these bonds are broken, the energy is released and used to synthesize ATP. The carbon, oxygen, and hydrogen atoms in carbohydrates are still present in the final products of cellular respiration, which are carbon dioxide and water. Therefore, cellular respiration involves a rearrangement of atoms and a transformation of energy, rather than the conversion of matter to energy.
