Question

Diffusion is an energy dependent processs

Answer 1

False

Diffusion is not an energy dependent processs

Answer 2

Diffusion is an energy dependent process

FALSE

Explanation:

• Active transport (secretion) is an energy-dependent process that selectively moves a substance against its electrochemical gradient across a cell membrane.

• It is an energy dependent process, in which ATP is utilized.

• An example of active transport is sodium and potassium pump.

• In this sodium is pumped out of the cell and potassium into the cell at the expenditure of energy. Active transport also takes place in the internal lining of the small intestine.

• Active transport takes place for the accumulating high concentration of molecules like ions, glucose, amino acids etc.
