Question

When does active transport occur in a cell?

Answer 1

Answer:

Active transport usually happens across the cell membrane. There are thousands of proteins embedded in the cell's lipid bilayer. Those proteins do much of the work in active transport. They are positioned to cross the membrane so one part is on the inside of the cell and one part is on the outside.

Active transport usually happens across the cell membrane. There are thousands of proteins embedded in the cells lipid bilayer . Those proteins do much of the work in active transport. They are positioned to across the membrane so one part is on inside of the cell and one part is on outside .Active transport is a moment of dissolved molecules into or out of the cell through cell membrane, from a region of lower concentration to a region of higher concentration.......Carrier proteins pick up specific molecules and take them through the cell membrane against the gradient.
