Answer: b. water
Explanation:
Cellular respiration is the set of biochemical reactions by which certain organic compounds are completely degraded, by oxidation, until they become inorganic substances, a process that provides usable energy by the cell (mainly in the form of ATP). The process involves the splitting of pyruvic acid (produced by glycolysis) into carbon dioxide and water, along with the production of adenosine triphosphate (ATP) molecules. In other words, cellular respiration involves a metabolic process by which cells reduce oxygen and produce energy and water. These reactions are indispensable for cellular nutrition.
The release of energy takes place in a controlled manner. Some of this energy is incorporated into ATP molecules which, thanks to this process, can be used in endothermic processes such as anabolism (the maintenance and development of the organism).
The products of cellular respiration are carbon dioxide and water, which are waste products. Carbon dioxide is transported from the mitochondria out of your cell, into the red blood cells, and back to the lungs to be exhaled. And ATP is generated in the process. When a glucose molecule is broken down, it can be converted into a net total of 36 or 38 molecules of ATP. This only occurs in the presence of oxygen.
