"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
The energy requiring process that moves material across a cell membrane against a concentration difference is called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
Movement across a membrane that does require energy is called active transport.
The movement of ions or molecules across a cellular membrane from a lower to a higher concentration, requiring the consumption of energy.
Active transport requires energy to move substances across a cell membrane against their gradient.
Facilitated diffusion across a biological membrane requires energy. Passive diffusion across a cellular membrane does not require any energy from the cell.
If the cell expends energy to actively transport material across the membrane we call that active transport.
to move the ions across the membrane,its neccassry to give the energy for to the ions.
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
Active transport is the energy to move substances. The substances moves across the plasma membrane.
