Bozeman Cell Transport

What are the two types of cell transport?

• Passive and Active

• Active and Facilitated

• Passive and Facilitated

• None of the above

In passive transport, substances move across the cell membrane ________ the concentration gradient

• AGAINST

• ALONG

• WITH

• BETWEEN

Which example describes diffusion?

• Water moving across a semi-permeable membrane

• Baking cookies and smelling them throughout the house

• Ions moving through an ion channel

• All of the above

What macromolecule is embedded into the lipid bilayer and helps to transport molecules?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid

Which describes a hypotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

The movement of particles from an area of high concentration to an area of low concentration

• active transport

• osmosis

• diffusion

• random movement

When material passes into and out of a cell at equal rates and there is no difference in concentration between the inside and outside of the cell, the cell is in a state of...

• dynamic equilibrium

• diffusion

• osmosis

• active transport

If a cell is placed in an environment with MORE oxygen OUTSIDE the cell than inside, the cell will...

• gain oxygen

• lose oxygen

• gain water

• lose water
