EOC Cell Transport

The movement of particles from an area of high to low concentration is known as--

• Passive Transport

• Active Transport

What is it called when large molecules move across the cell membrane from an area of high concentration to an area of low concentration through a protein channel?

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

Which is true about active transport?

• It requires energy

• It does not require energy

• It moves substances down the concentration gradient

• it moves material from high to low concentration

If the dots represent sugar which is more concentrated

• Inside the cell

• Outside the cell

• Neither they are equal (equilibrium)

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

​ (a)   brings glucose into cells.

• Insulin

• Glucagon

• Glycogen

Match the following vocabulary terms and definitions.

• Isotonic

• Low concentration; the solution has less solutes than the cell, causing water to move into the cell and out of the solution.

• Hypotonic

• High concentration; the solution has more solutes than the cell, causing water to move out of the cell and into the solution.

• Hypertonic

• Same concentration; the solution and cell have equal concentration of solutes (particles), so water moves equally between the cell and solution.

What type of solution is this cell in?

• diffused
