Where is cytochrome found?

Cytochrome:

1. Cytochromes are hemoproteins with heme groups that are responsible for generating ATP through electron transport.
2. They exist as monomeric proteins (for example, cytochrome c) or as subunits of larger enzyme complexes that catalyze redox processes.
3. MacMunn first identified cytochromes as respiratory pigments in $1884$.
4. They are found in mitochondrial cristae.
5. Cytochrome is a protein family that contains an iron-containing heme group.
6. They are found in mitochondria (cristae) and chloroplasts as part of the electron transport chain (in thylakoids).
7. Cytochrome is found in the inner mitochondrial membrane.
