Cytochromes are found in:

1. Outer wall of mitochondria
2. Cristae of mitochondria
3. Lysosomes
4. Matrix of mitochondria

Correct answer: Cristae of mitochondria

Solution

Cytochromes function in the electron transport chain, which is located on the inner mitochondrial membrane. The inner membrane folds form the cristae, so that is where cytochromes are found.
