Question

Assertion : Oxidative phosphorylation requires oxygen.
Reason : Oxidative photophosphorylation occurs in mtiochondria.
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 reasons are true but reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer 1

Correct Answer - B
The synthesis of ATP via electron flow through the ETS, with oxygen as the terminal electron acceptor, is known as oxidative phosphorylation and takes place in mitochondria. In contrast to the oxidative phosphorylation of mitochondria, `O_(2)` is not used in photophosphorylation of chloroplasts and `NADP^(+)` is last electron acceptor.
