Question

facilitated diffusion is used to transport ____________. multiple choice sugars and amino acids h₂o and o₂ co₂ and o₂ co₂ and h₂o sugars and h₂o

Explanation:

Facilitated diffusion uses transport proteins to move substances across the cell - membrane. Small, non - polar molecules like O₂, CO₂ can diffuse freely across the membrane by simple diffusion. Water can also cross by simple diffusion or aquaporins in some cases. However, polar molecules like sugars and amino acids are transported across the membrane via facilitated diffusion.

Answer:

A. sugars and amino acids
