Answer #1

* The answer is transport protein.

* Facilitated diffusion is a process in which substance move down to its concentration gradient( higher to lower concentration) using a transport protein. Large insoluble membrane compounds like sugars(glucose) and amino acids undergoes facilitated diffusion.

* facilitated diffusion doesn't require ATP as it is a passive diffusion(doesn't need energy).

* Sodium-potassium pump and vesicle transport comes under active transport(requires energy).

Select the statements that describe the operation of the sodium–potassium pump. (More then one statement is correct) The sodium–potassium pump transports sodium and potassium down their concentration gradients. For every two sodium ions pumped out of the cell, three potassium ions are pumped into the cell. For every exchange of sodium and potassium ions, one ATP molecule is hydrolyzed. The sodium–potassium pump actively transports ions across the membrane, which maintains homeostasis.
