Question

small proteins and amino acids ____ diffuse through a lipid bilayer by themselves, without the aid of a channel or transporter. cannot can question 6 1 pts simple diffusion is used for: sucrose oxygen sugar

Explanation:

Small proteins and amino acids are polar and relatively large compared to molecules that can pass through lipid bilayers by simple diffusion, so they cannot diffuse through unaided. Oxygen is a small, non - polar molecule that can pass through the lipid bilayer by simple diffusion, while sucrose and sugar are larger polar molecules that require transporters for membrane passage.

Answer:

1. cannot
2. oxygen
