Proteins P, Q, and R are associated with intact organellar membrane in a cell. If the intact organellel is treated with a high ionic strength buffer, only protein R remained associated with the membrane fraction. Based on this, one could conclude that
(A) P and Q are peripheral membrane proteins.
(B) R is a peripheral membrane protein.
(C) P and Q are integral membrane bound proteins.
(D) P is peripheral and Q is integral membrane protein.
Correct option (A) P and Q are peripheral membrane proteins.
Explanation:
Peripheral proteins can be detached earily
