Where the cytochrome - c is located ? Write its function.

Explanation

### Step-by-Step Solution

1. **Location of Cytochrome C**:
- Cytochrome C is located on the inner surface of the inner mitochondrial membrane. This membrane is crucial for the process of cellular respiration as it houses the electron transport chain.

2. **Function of Cytochrome C**:
- The primary function of Cytochrome C is to transfer electrons within the electron transport chain. Specifically, it acts as a bridge between Complex III (cytochrome BC1 complex) and Complex IV (cytochrome C oxidase). By facilitating this electron transfer, Cytochrome C plays a vital role in the process of oxidative phosphorylation, which ultimately leads to the production of ATP.
