The meaning of PASSIVE TRANSPORT is the movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
上文描述Unfortunately, this kind of transport requires the cell to work against the natural direction of diffusion, so the cell uses up energy.可知此处举例描述。 1. B 【解析】本题考查考生逻辑推理能力。根据下一句They must have water, oxygen, sugar, sodium, potassium(钾), and a variety of ...
of cellular energy. Active transport uses carrier proteins that act as a pump to move ions and molecules across the membrane. The sodium-potassium pump in animals is an example of this. It moves sodium out of the cell and potassium into it using about one third of its total energy budget...
ATP) is not required as it is in active transport. Rather, passive transport utilizes kinetic and natural energy to drive the movement. Conversely, in active transport, the movement is uphill, meaning they move from an area where they are less in number to an area where they already are ...
