Tonicity Review

What is the difference between active and passive transport?

• Active is high to low; Passive is low to high

• Active uses no cell energy; Passive uses cell energy

• Passive is high to low and uses no energy; Active uses energy and is low to high

• Passive uses no cell energy

What are the types of passive transport? Select all that apply.

• Simple diffusion

• Facilitated diffusion

• Endocytosis

• Osmosis

• Protein pumps / carrier proteins

What is the movement of particles with the concentration gradient using protein "helpers"?

• diffusion

• facilitated diffusion

• active transport

• enzymatic reactions

Some cells move large particles out of the cell through the process of:

Active transport is when molecules move ________ the concentration gradient.

• against

• up

• down

• with

This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
