Question

Differentiate active and passive transport.

Answer 1

• In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP( energy).

(1 mark)

• In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).

• Active transport is highly selective whereas passive transport is partly non-selective.
