Question

Potassium cyanide is known to interfere with the formation and use of ATP in cell metabolism.
If the use of potassium cyanide resulted in an accelerated entry of a solute into a cell, it may be reasonably assumed that, under normal circumstances, the solute enters by?

• A. Active transport
• B. Osmosis
• C. Passive diffusion
• D. Pinocytosis

Answer 1

Answer: (A)

Active transport

(A)Active transport is the movement of molecules which requires energy.

(B)Osmosisis the movement of molecules from higher concentration to lower concentration through the semi-permeable membrane.

(C)Passive diffusion is the movement of molecules which does not require energy.

(D)Pinocytosis is the ingestion of liquid into a cell by the budding of small vesicles from the cell.

So, the correct option is 'Active transport'.
