Assertion : In electron transport system, the electrons are passed on to oxygen resulting in the formation of `H_(2)O`
Reason : Oxygen is the ultimate acceptor of electrons.

Options

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

Answer

a

Explanation

Oxgyen is the terminal electron acceptor of respiratory chain. In electron transport system, electrons are passed on from one carrier to another and ultimately to oxgyen and at the end of this chain, one molecule of water is produced as:
`(1)/(2) O_(2) + 2H^(+) + 2e^(-) rarr H_(2)O`
