How the Kerbs cycle acts as central pathway of respiration ?

Explanation

**Step-by-Step Solution:**

1. **Definition of the Krebs Cycle**: The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

2. **Location of the Krebs Cycle**: The Krebs cycle occurs in the mitochondria of eukaryotic cells. It acts as a central hub in cellular respiration, positioned between glycolysis and the electron transport chain (ETC).

3. **Connection to Glycolysis**: Glycolysis is the first step of cellular respiration, occurring in the cytoplasm, where glucose is broken down into pyruvate. The pyruvate then enters the Krebs cycle if oxygen is present, linking the two processes.
