Final answer:
The correct sequence of cellular respiration stages is: Glycolysis, Acetyl CoA Formation, Krebs Cycle, and Electron Transport Chain.
Step-by-step explanation:
The stages of cellular respiration should be arranged in the following sequence: Glycolysis → Acetyl CoA Formation → Krebs Cycle → Electron Transport Chain. Therefore, the correct order from the options provided is:
- Glycolysis → Acetyl CoA Formation → Krebs Cycle → Electron Transport Chain
This order represents the sequential flow of carbon compounds and electrons as they are utilized in energy extraction from glucose. Glycolysis occurs first in the cytoplasm where a glucose molecule is broken down into two pyruvate molecules. Then, in the presence of oxygen, pyruvate enters the mitochondria where it is transformed into Acetyl CoA. Acetyl CoA then enters the Krebs Cycle, which occurs in the mitochondrial matrix. Finally, high-energy electron carriers produced from the first two stages donate electrons to the Electron Transport Chain on the inner mitochondrial membrane to drive ATP synthesis.
