Question

particles move across the to provide nutrients to the cell and to get rid of waste, such as carbon dioxide. when diffusion occurs, particles move from areas of concentration to areas of low concentration. no atp is required for diffusion to occur. diffusion is an example of transport. some materials must move from areas of low concentration to high concentration, which requires. the sodium - potassium pump is an example of a process requiring energy and is referred to as. passive proteins neutral moveable active automatic high cell membrane atp

Explanation:

Particles move across the cell membrane for nutrient - supply and waste - removal. Diffusion is from high to low concentration and is passive transport. Movement from low to high concentration requires ATP and is active transport.

Answer:

cell membrane, high, passive, ATP, active
