The main difference between active and passive transport across cell membrane is:

1. active transport occurs more rapidly than passive transport.
2. passive transport is non-selective whereas active transport is selective.
3. passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes.
4. passive transport is confined to anionic carrier proteins whereas active transport is confined to cationic channel proteins.
