Final answer:
The processes involved are photosynthesis (in plants) and respiration (in animals including humans). Through these processes, glucose and oxygen are converted to energy, carbon dioxide, and water. These two processes are part of the larger cycle of life.
Step-by-step explanation:
The subject in question is related to a biological process, specifically that of respiration and photosynthesis. When you eat food, the reactant C6H12O6 (glucose) enters your body. Through breathing, another reactant, 6O2 (oxygen), comes into your system. In response to this, your body initiates a process of respiration wherein glucose and oxygen are used to generate energy, with 6CO2 (carbon dioxide) and 6H2O (water) being the byproducts. This carbon dioxide is then exhaled out of the body.
The same molecules, but in reverse, are part of the process of photosynthesis in plants. In photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using energy from sunlight. Therefore, in this sense, photosynthesis and respiration can be seen as complementary processes in the larger cycle of life.
