Which one of the following molecules would be most likely to travel by facilitated diffusion? A. sodium ions B. glucose C. oxygen atoms

The correct answer is : the sodium ion and glucose both shows the facilitated diffusion.

Explanation:

Facilitated diffusion is form of diffusion of molecules of solutes with the help of transport proteins along their concentration gradient on the plasma membrane, however it is a passive transport as its does not require energy to move in or out of cell.

Oxygen can move through the membrane directly by simple mean of diffusion. however, Other molecules like amino acids, ions, glucose and many more need a integral pore, channel or transport molecule to pass through the membrane or with facilitated diffusion.

Glucose transporters involves to help in movement of glucose through the membrane along the concentration gradient it shows facilitated diffusion. Sodium ions also move through along concentration gradient by protein channels formed by transport proteins through hydrophobic membrane.

Thus, the sodium ion and glucose both shows the facilitated diffusion.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
