Question

Cytochrome C structure Cytochrome C is a protein found in all species, and functions in energy metabolism. The more closely related two different species are,

A. ances the greater the number of accumulated mutations will have occurred in their cytochrome C molecules.
B. the greater the differences in oxygen utilization in energy metabolism the more like their cytochrome Camino acid sequences are.
C. the greater the number of differences there are in their amino acid sequences in cytochrome C.

Answer 1

Cytochrome C is a protein found in all species, and functions in energy metabolism. The more closely related two different species are,

C. the greater the number of differences there are in their amino acid sequences in cytochrome C.

Step-by-step explanation:

Cytochrome c, unlike other cytochromes, is highly water-soluble. It is an essential component of the electron transport chain, where it transfers electrons between complex III and complex IV of the respiratory chain. It undergoes oxidation and reduction when its iron atom converts between the ferrous forms to the ferric forms, but it does not bind to oxygen.
