Assertion : `Na^(+)- K^(+)` ATPase is an important membrane associated enzyme.
Reason : It helps in ion transfer across the memrbane.

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 if false
D. If both the assertion and reason are false

Answer

A

Explanation

Of all the membrane associated enzymes, `Na^(+),-K^(+)` ATPase is one of the most important because of its role in ion transfer across the plasma membrane. This enzyme is dependent on the presence of lipids and is inactivated when all lipids are extracted.
