FAQs on More about Oxygen Video Lecture - Science Class 6
| 1. What is oxygen? |  |
Ans. Oxygen is a chemical element with the symbol O and atomic number 8. It is a highly reactive gas and is essential for the survival of most living organisms. Oxygen is a key component of air, making up around 21% of the Earth's atmosphere.
| 2. How does oxygen support life? | |
Ans. Oxygen supports life by being a vital component of cellular respiration, the process by which cells convert glucose into energy. In this process, oxygen acts as the final electron acceptor in the electron transport chain, allowing cells to produce ATP (adenosine triphosphate), which is the energy currency of the body.
| 3. What are the sources of oxygen? | |
Ans. The primary source of oxygen on Earth is through photosynthesis, a process carried out by plants, algae, and some bacteria. During photosynthesis, these organisms convert carbon dioxide and sunlight into glucose and oxygen. Additionally, oxygen is also released during the electrolysis of water and can be obtained from air separation processes.
| 4. Why is oxygen important for combustion? | |
Ans. Oxygen is essential for combustion because it acts as an oxidizing agent. Combustion is a chemical reaction that occurs when a fuel (such as wood or gasoline) combines with oxygen in the presence of heat. Oxygen molecules break down the fuel molecules, releasing energy in the form of heat and light.
| 5. How is oxygen transported in the human body? | |
Ans. In the human body, oxygen is primarily transported through the bloodstream. It binds to hemoglobin, a protein found in red blood cells, forming oxyhemoglobin. This oxygen-rich blood is then pumped by the heart to various tissues and organs, where oxygen is released to support cellular respiration and energy production.
