Question

A hormone has bound to its receptor embedded in membrane of its targeted cell.movement of glucose into cell as a result of hormone binding to its receptor is :
a) facilitated diffusion
b) diffusion
c) active transport
d) pasdive diffusion​

Answer 1

Answer:

a) Facilitated diffusion

As the transportation is by special membrane protein without expense of ATP.

hope this will help you

Answer 2

Answer: The correct answer to this question is (A) Facilitated Diffusion

Explanation:

Facilitated diffusion transport, similar to passive transport, includes the transport of molecules and ions according to their concentration across the cell. No outer sources of energy is given, so particles traverse the cell membrane as per the concentration gradient and, on account of charged atoms, by the electric potential across the layer.

Also, this type of transport varies from passive dispersion in that the moved atoms don't break down in the phospholipid bilayer. Because, their transport is intervened by proteins that allow the moved particles to cross the layer without connecting with its hydrophobic part.

Facilitated transport hence permits polar and charged particles, like sugars, amino acids, nucleosides, to cross the plasma layer.

Transporter proteins are main molecule for the Facilitated diffusion of sugars, amino acids, and nucleosides across the plasma layers of most cells. The take-up of glucose, which fills in as an essential wellspring of metabolic energy, is one of the main vehicle elements of the plasma layer.
