Question

match each of the following processes to the substances being moved. (this is a test question))
substances from high to low area concentration
water from high area to low area concentration
ions from low to high area concentration
large particles
endocytosis sodium - potassium atpase pumps osmosis diffusion

Explanation:

• Diffusion: It is the movement of substances (other than water) from an area of high concentration to an area of low concentration.
• Osmosis: Specifically refers to the movement of water from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration).
• Sodium - potassium ATPase pumps: These are active transport mechanisms. Active transport moves ions (like sodium and potassium ions in this case) from an area of low concentration to an area of high concentration, and it requires energy (in the form of ATP).
• Endocytosis: It is a process by which cells engulf large particles (such as bacteria, food particles etc.) by forming vesicles around them.

Answer:

• substances from high to low area concentration: diffusion
• water from high area to low area concentration: osmosis
• ions from low to high area concentration: sodium - potassium ATPase pumps
• large particles: endocytosis
