Вопрос 116

Which statement correctly classifies the energy requirement of osmosis?

  1. It always consumes ATP at membrane pumps.
  2. It requires no direct cellular energy input.Правильный ответ
  3. It occurs only while a cell is respiring rapidly.
  4. It is powered by contraction of the cell membrane.

Объяснение

Osmosis is passive, with net water movement arising from a water-potential difference rather than direct cellular energy use. Energy-powered solute pumping can create gradients, but that does not make the water movement itself ATP-driven.
