- Question
Is Osmosis Active or Passive?
- Correct Answer
- Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane It doen't requires any additional energy to do this work So, Osmosis is a Passive Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes 1 Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required 2 Passive transport is the movement of molecules or ions from an area of higher to lower concentration Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur 3 Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur
