Where are the enzymes of the electron transport system found?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Electron Transport System (ETS):** The electron transport system is a series of complexes that facilitate the transfer of electrons, ultimately leading to the production of ATP through oxidative phosphorylation.

2. **Identifying the Complexes:** The ETS consists of five main complexes, commonly referred to as Complex I through Complex V. Each of these complexes plays a crucial role in the electron transport chain.

3. **Location of the Complexes:** These complexes are located in a specific part of the cell. In eukaryotic cells, particularly in plants and animals, the electron transport system is found in the mitochondria.
