The Correct Answer and Explanation is :
General Equation for Cellular Respiration:
The correct general equation for cellular respiration is:
[
\text{C}6\text{H}{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{ATP}
]
Explanation:
Cellular respiration is the process by which cells convert glucose ((\text{C}6\text{H}{12}\text{O}_6)) and oxygen ((\text{O}_2)) into energy, releasing carbon dioxide ((\text{CO}_2)) and water ((\text{H}_2\text{O})) as byproducts. This process occurs in both plant and animal cells, mainly inside the mitochondria.
- Glycolysis – The first step occurs in the cytoplasm, where glucose is broken down into two molecules of pyruvate, producing a small amount of ATP and NADH.
- Krebs Cycle (Citric Acid Cycle) – The pyruvate enters the mitochondria, where it undergoes oxidation. This cycle generates high-energy electron carriers (NADH and FADH(_2)) and releases (\text{CO}_2).
- Electron Transport Chain (ETC) and Oxidative Phosphorylation – NADH and FADH(_2) transfer electrons through a series of proteins in the inner mitochondrial membrane. This movement of electrons drives the production of ATP using oxygen as the final electron acceptor, producing (\text{H}_2\text{O}) as a byproduct.
Oxygen’s Role:
Oxygen is essential in the final step of the ETC, where it acts as the final electron acceptor. Without oxygen, ATP production is significantly reduced, leading cells to rely on anaerobic respiration, which is far less efficient.
Thus, the correct statement is:
“The (\text{O}_2) required for cellular respiration is supplied by breathing.”
Now, I will generate an image representing cellular respiration.
Here is a detailed diagram of cellular respiration, illustrating glycolysis, the Krebs cycle, and the electron transport chain, along with the movement of key molecules like glucose, oxygen, CO₂, H₂O, and ATP. Let me know if you need any modifications or further explanations!
