Web12 sep. 2024 · Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient. Active transport is an energy-driven process where membrane proteins transport molecules across cells, mainly classified as either primary or secondary, based on how energy is coupled to fuel these mechanisms. WebOsmosis is defined as the movement of water from an area of high water potential to an area of low water potential through a partially permeable membrane. As active transport needs ATP, you can see why waterlogged plants cause issues. Waterlogged plants cannot obtain oxygen, and this severely reduces the rate of aerobic respiration.
