Q. A group of students are studying transport of certain type of molecules in a cells and observe that transport slows down when the cells are treated with poison, a chemical, which inhibit energy production. Under normal conditions, the molecules are being studied and it is estimated that molecules probably transported by
A) Osmosis
B) Process of active transport
C) Process of facilitated diffusion
D) Process of simple diffusion
Explanation
In active transport, the movement of solutes occur against the concentration gradient or chemical potential gradient with the expenditure of energy
