Define the following terms:
$(i)$ Passive transport
$(ii)$ Facilitated diffusion
$(i)$ Passive transport
$(ii)$ Facilitated diffusion
(N/A) $(i)$ Passive transport: This process occurs along the concentration gradient,i.e.,from a region of higher concentration to a region of lower concentration,and it does not require any metabolic energy $(ATP)$.
$(ii)$ Facilitated diffusion: This process also occurs along the concentration gradient,but it requires specific membrane proteins (carrier molecules) to act as mediators to transport molecules across the membrane.
