How does active transport differ from passive

gradient in active transport.
2. Carrier proteins are used only in active
3. Energy is required only in active transport.
4. Energy is required only in passive transport
Unfortunately, Jiskha doesn't have a regular biology tutor.
i believe the answer is #1
It is not #1. That is a definition of diffusion.
oh my bad. sorry. biology was always tough for me
The answer would be 3.
