Cytochromes are defined as:

The process by which $ATP$ is produced in the inner membrane of a mitochondrion,where the electron transport system transfers protons from the inner compartment to the outer,and as the protons flow back to the inner compartment,the energy of their movement is used to add phosphate to $ADP$,forming $ATP$,is known as:
