________ Is/are the Substance(s)involved in Facilitated Diffusion

Question

________ is/are the substance(s)involved in facilitated diffusion.
A) Only water
B) Glucose and amino acids
C) Lipid-soluble materials
D) Small organic ions and molecules
E) Extracellular fluid

Accepted Answer

Glucose and amino acids are the substances involved in facilitated diffusion. Facilitated diffusion is a type of passive transport where specific proteins called transporters or carriers help move molecules across the cell membrane from an area of higher concentration to an area of lower concentration. The transporters have specific binding sites for the molecules they transport, and they undergo a conformational change to move the molecules across the membrane. Glucose and amino acids are examples of molecules that require transporters for facilitated diffusion.
