ETC is component of

Options

A. Golgi apparatus
B. Mitochondria
C. Nucleus
D. Micoutubules

Answer

**Step-by-Step Solution:**

1. **Understand the acronym ETC**: The question refers to "ETC," which stands for the electron transport chain.

2. **Identify the function of the electron transport chain**: The electron transport chain is a series of complexes that transfer electrons through a membrane within the mitochondria. This process is crucial for ATP (adenosine triphosphate) generation, which is the energy currency of the cell.

3. **Locate where the electron transport chain is found**: The electron transport chain is specifically located on the inner membrane of the mitochondria.

4. **Relate the function to the organelle**: Since the electron transport chain is involved in the final steps of cellular respiration and ATP production, and it is located in the mitochondria, this organelle is often referred to as the "powerhouse of the cell."

5. **Choose the correct option**: Given the options provided (Golgi apparatus, mitochondria, nucleus, or microtubules), the correct answer is mitochondria, as it is the organelle that contains the electron transport chain.

**Final Answer**: ETC is a component of **mitochondria** (Option B).
