Understanding the Redox Equation

The given redox equation is: ${ \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{H}_2\text{O} + 6\text{CO}_2 \}$

This equation represents a chemical reaction where a substance is oxidized and another substance is reduced. In this case, glucose (C6H12O6) is the substance being oxidized, and oxygen (O2) is the substance being reduced.

Oxidation and Reduction

Oxidation is a process where a substance loses one or more electrons, resulting in an increase in its oxidation state. Reduction, on the other hand, is a process where a substance gains one or more electrons, resulting in a decrease in its oxidation state.

In the given equation, glucose is losing electrons to oxygen, resulting in the formation of carbon dioxide (CO2) and water (H2O). This is an example of oxidation, as glucose is losing electrons.

Cellular Respiration

Cellular respiration is a process by which cells generate energy from the food they consume. It involves the breakdown of glucose and other organic molecules to produce ATP (adenosine triphosphate), which is the primary energy currency of the cell.

The given redox equation is a key step in cellular respiration, specifically in the process of aerobic respiration. In this process, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, releasing energy in the form of ATP.

Combustion

Combustion is a process where a substance reacts with oxygen to produce heat and light. It is often accompanied by the release of carbon dioxide and water.

While the given redox equation does involve the reaction of glucose with oxygen, it is not an example of combustion. Combustion typically involves the rapid release of heat and light, whereas the given equation represents a more controlled process.

Photosynthesis

Photosynthesis is a process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It involves the absorption of carbon dioxide and release of oxygen.

The given redox equation is the reverse of photosynthesis. In photosynthesis, carbon dioxide is converted into glucose, releasing oxygen as a byproduct. In the given equation, glucose is converted into carbon dioxide and water, consuming oxygen in the process.

Rusting

Rusting is a process by which iron and its alloys react with oxygen and moisture to form iron oxide. It is a type of oxidation reaction.

The given redox equation does not involve iron or any other metal, so it is not an example of rusting.

Conclusion

Based on the analysis of the given redox equation, it is clear that the process represented is cellular respiration. The equation shows the breakdown of glucose in the presence of oxygen to produce carbon dioxide and water, releasing energy in the form of ATP.

The other options, combustion, photosynthesis, and rusting, do not accurately represent the process shown in the given equation.

Key Takeaways
