[GP] Q.6.) Difference between active & passive transport.

Ans. Active transport(primary active trasport & secondery active transport):S

1.Carrier protein needed.

2.Utilization of energy.

3.Enzyme needed.

4.Substances moves against concentration gradient(i.e.from lower to higher conc.).

5.Substances moves against electrochemical gradient.

Passive transport(osmosis & diffusion):

1. 1.Usually no need of Carrier protein(except faciliated diffusion).S

2. No need of energy.

3.Substances moves along the electrochemical gradient. (i.e.from higher to lower conc.).
