What are the different methods of transport across a membrane ?
dusya [7]
If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.

Active transport moves up the concentration gradient and does require energy.


Perhaps someone who has taken bio within the last several years can correct anything I might have misstated here.
