Question

1. simple diffusion and facilitated diffusion are related in that both use energy in the form of atp move molecules from areas of high concentration to low concentration occur in eukaryotic cells but not in prokaryotic cells require transport proteins 11. which process allows small molecules, like oxygen, to pass through a cell membrane without using energy or a protein? active transport endocytosis simple diffusion facilitated diffusion

Explanation:

1. Simple diffusion and facilitated diffusion are passive - transport mechanisms. They move molecules from an area of high concentration to an area of low concentration without using ATP. Facilitated diffusion uses transport proteins while simple diffusion doesn't, but both follow the concentration gradient.
2. Simple diffusion is the process by which small, non - polar molecules like oxygen can pass through the cell membrane without the use of energy (ATP) or a transport protein. Active transport requires energy, endocytosis is a process of taking in large particles, and facilitated diffusion requires a transport protein.

Answer:

1. move molecules from areas of high concentration to low concentration
2. Simple Diffusion
