Enzymes can

  • A.not pass through semipermeable membrane
  • B.pass through semipermeable membrane
  • C.dissolve semipermeable membrane
  • D.none of these

Answer: A

Correct answer: not pass through semipermeable membrane

Enzymes are large protein molecules, far too big to cross a semipermeable membrane. That is what keeps them inside the cell or the organelle where they belong, and it is why a cell must secrete an enzyme deliberately if it is to act outside.
