Who am I?
Key Points:
- Present in the air
- Needed by the human body to produce energy
- Enters the lungs when breathing in
The answer to the question is Oxygen. Here's a detailed explanation:
Present in the air:
- Oxygen is one of the main components of the Earth's atmosphere.
- It makes up about 21% of the air we breathe.
Needed by the human body to produce energy:
- Oxygen is essential for cellular respiration, which is the process by which our cells produce energy.
- During respiration, oxygen is used to break down glucose and other molecules, releasing energy in the form of ATP.
Enters the lungs when breathing in:
- When we inhale, air enters our lungs through the respiratory system.
- The oxygen in the air diffuses into the bloodstream through the alveoli in the lungs, where it binds to hemoglobin in red blood cells.
- The oxygen-rich blood is then pumped to various parts of the body to provide energy.
Therefore, based on the given information, the correct answer is Oxygen (D).
