Options:
  • A passive transport is non-selective whereas active transport is selective
  • B passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes
  • C passive transport is confined to anionic carrier proteins whereas active transport is confined to cationic channel proteins
  • D active transport occurs more rapidly than passive transport

The correct answer is: passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes
The main difference between active and passive transport across the cell is that passive transport requires concentration gradient across biological membrane whereas during active transport, the movement of molecules is from high concentration to low concentration that means they move against the concentration gradient by using ATP.
