The main difference between active and passive transport across...

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

Options

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

Correct answer

B. passive transport requires a concentration gradient across a biological membrane whereas active transport requires energy to move solutes

Step-by-step solution

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.
