Cell Transport

In a nerve cell, ATP energy is used to pump sodium (Na) out of the cell and potassium (K) into the cell. This is an example of...

• Diffusion

• Active Transport

• Osmosis

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell.

• concentration gradient

• equilibrium

• passive transport

• active transport

A cell moves particles using energy against the concentration gradient by

• active transport

• passive transport

• diffusion

• osmosis

Which of the following are characteristics of passive transport? (Select all that apply.)

• High to Low Concentration

• Does NOT require energy

• Applies to liquids only

• Involves smaller molecules, like oxygen, carbon dioxide, and water

Which of the following is true of active transport? (Select all that apply.)

• Requires energy

• Only involves the movement of gasses

• Low to High Concentration

• Involves larger molecules, like glucose (sugar) and proteins

Which of the following are types of passive transport? (Select all that apply.)

• Diffusion
