MCQ

Question

Suppose you were to treat a normal mammalian cell with a substance that inhibits the Na-K ATPase, what would be the most immediate effect upon the cell ?

Options

Choose one · Correct answer highlighted

there would be no change at all the cell’s osmotic balance would be disrupted and the cell would begin to swell the cell membrane potential would immediately drop to zero Correct the cell would very quickly run out of ATP

Explanation

Mechanistically, enzyme catalysis and lipid structure involves substrate affinity, transition state stabilization and phospholipid composition govern function. This validates the cell membrane potential would immediately drop to zero because it reflects catalytic efficiency and membrane organization, a pattern repeatedly demonstrated in biochemistry research.
