Question

Glucose and amino acids move in or out of a cell by _____.

passive diffusion
facilitated diffusion
active transport
endocytosis and exocytosis

Answer 1

Glucose and amino acids move in or out of a cell by facilitated diffusion.

Answer: B) or the second option.

Answer 2

The correct answer is:

facilitated diffusion.

Glucose and amino acids move in or out if a cell by facilitated diffusion. Facilitated diffusion is the passive transport of molecules, ions, and particles towards a specific membranous protein.

Explanation:

Facilitated diffusion is the means of spontaneous passive transport of molecules or ions crossed a biological membrane through distinct transmembrane integral proteins. In the cell, examples of molecules that necessity uses expedited diffusion to move in and out of the cell membrane are glucose, sodium ions, and potassium ions. They pass using carrier proteins through the cell membrane without power near the concentration gradient.
