It is because active transport requires energy for it to work.
Active Transport
Active transport requires energy to move a molecule.
ATP supplies the energy for active transport.
Active transportation is taken place against concentration gradient. So this requires energy .
Yes, require to spend energy
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
Active transport uses ATP as an energy source.
Active transportation need energy.That energy is given by ATP.
Active Transport..........
I believe it's active transport. active transport is correct.
active transport
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Passive transport... the opposite of active transport.
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
Active transport requires energy to move the ions against the gradient. This energy is release during the process of respiration.
Active transport requires energy in the form of ATP
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
