Compare and contrast facilitated and active transport? What will be an ideal response?
Both of these have in common that they move substances across cell membranes via transmembrane
proteins. However, facilitated transport can only move substances down their concentration gradient.
Whereas in active transport, movement can be against the concentration gradient. Facilitated transport
requires no ATP energy. On the other hand, active transport does requires ATP energy.
