Question

The movement of water across a cell membrane is active transport and requires a lot of energy. True False

Answer 1

False. The movement of water across a cell membrane is primarily facilitated by passive transport processes, specifically osmosis, which does not require energy. Active transport, on the other hand, generally involves the movement of ions or molecules against their concentration gradient and requires energy, often in the form of ATP. Water typically moves along its concentration gradient without the direct use of energy.
