Assertion: Cytochromes are a group of copper containing electron transferring proteins.
Reason: The terminal cytochrome reacts with oxygen.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If the assertion is false but the reason is true

Answer

D

Explanation

Cytochrome is hence containing protein in the intermembrane space. In addition to their iron atoms, cytochromes a and 3 a contain a single copper atom bound to their hence group. It associates with the iron atom to form bimetallic iron copper `(F_(e)- Cu)` center copper ions can be reversibility converted from the oxidized `(Cu^(2+))` to the reduced form `(Cu^(+))` by accepting or donation single electrons. Oxygen acts as a terminal electron acceptor. It becomes reactive and combines with protons to form metabolic water.
