Definition: Given a passage and a query based on the passage, generate an unambiguous, concise and simple answer to the query from information in the passage. Note that the answer may not be present in exact form.
Input: Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes. 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. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. There are multiple forms of passive transport: simple diffusion, facilitated diffusion, filtration, and osmosis. Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur. Compare. Both active and passive transport move materials and can cross biological membranes. Contrast Passive transport of water across a cell membrane. Movement of water is from a higher concentration of water (not solute) to lower concentration of water. Water passes easily through the lipid bilayer. Active transport to pump out water and/or solutes. Most cells in multicellular organisms are bathed in solutions that are not much different inside and out of the cell. Some unicellular organisms can move to different environments. In osmosis, the solvent (usually water) moves across a membrane to dilute the solute particles. 1 Article. 2 Article. 3 Article. 4 Article. 5 Article. 6 Article. 7 Article. 8 Article. 1. How do passive and active transport differ from each other? Passive transport Does not require the use of energy. Moves solutes and solvents across a cell membrane, from higher to lower concentration. Simple diffusion passive transport of small solutes thru the lipid bilayer. Facilitated diffusion transfer of larger molecules thru carrier or channel proteins. Osmosis diffusion of water thru the lipid bilayer. Active Transport a. Water will move out of the cell b. Water will move into the cell c. Fructose and glucose will move into the cell d. There will be no net movement of solutes e. There will be not net movement of water Contrast. 1 Active transport moves materials from lower to higher concentration, while passive transport moves materials from higher to lower concentration. 2 Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur. Active Transport Solutes move from a region of low concentration to high concentration. Active transport moves materials from lower to higher concentration, while passive transport moves materials from higher to lower concentration. Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur.
