Which type of transport requires energy?

Active transport requires energy. Passive transport does not require energy. In case you did not know active transport is the movement of ions or molecules across a cellular membrane from a lower to a higher concentration.
Hope this helps!

Active transport, requires ATP energy. 

The other type of cell transport is passive, which allows molecules/atoms to move down their concentration gradient, using no energy.
if it help pick as best tnxxx :)

The 3 steps are vasoconstriction, temporary blockage of a platelet plug, formation of a fibrin clot better known as coagulation.
