Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is NOT an active transport process?:
A
bulk transport
B
solute pumping
C
pinocytosis
D
facilitated diffusion
Explanation: 

Detailed explanation-1: -Osmosis, diffusion and facilitated diffusion are some of the examples of passive transport . Thus, facilitated diffusion is not an example of active transport because it does not require energy for transport of molecules.

Detailed explanation-2: -Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process, i.e., the membrane allows only selective molecules and ions to pass through it. It, however, prevents other molecules from passing through the membrane.

Detailed explanation-3: -Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
