Answer #1

Answer : None of these answer are correct.

Explanation :
For Passive transport ,Higher concentration to lower concentration movement occur only where for active transport both lower to higher concentration movement and vice versa occur because of due to use of energy (ATP) . So active transport only require ATP driven protien pump. So both option A and C are wrong.

Active transport can concentrate solute on one side of surface that arise because of concentration gradient difference.Passive transport can't do this because the flow of solute occur from high concentration to lower up to when pressure gradient is equal.so there is no chance of acumulation.so option B is incorrect also.

Active transport require protien for facilitate transport. Some time , Passive transport require protien.But it is not applicable for passive transport always. So the option E is wrong.


Hope it clear your doubt. Thank you

    Please summarize this chapter typed clearly. Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...
