Cell Transport

Front

Particle of movement from an area of lower concentration to an area of higher concentration.

Back

Active transport

Front

Particle of movement from an area of higher concentration to an area of lower concentration.

Back

Passive transport

Front

Which type of passive transport uses transport proteins to transport items such as glucose through the membrane?

Back

Facilitated diffusion

Front

In which case would a cell most likely shrink? Options: when placed in a solution containing a high salt concentration, when placed in a isotonic solution, when placed in a solution containing a low pH, when placed in a solution containing distilled water

Back

when placed in a solution containing a high salt concentration

Front

The tails of a phospholipid are meaning that they are "water-hating" because they are

Back

Hydrophobic, non-polar

Front

Acts as a membrane stabilizer, in particular when temperatures are high or low.

Back

Cholesterol

Front

A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. What has occurred?

Back

The water in the gums has moved out due to the high concentration of salt in the solution.

Front

Concentration gradient

Back

A difference in concentration over a distance

Front

"Channel proteins" in the membrane form tunnels through which molecules too large to move through the membrane can pass in and out of the cell. This is called ______

Back

Facilitated Diffusion

Front

Protein pumps on the membrane use energy to pick up molecules outside the cell, where the concentration is low, and move them inside, where the concentration is high. This is an example of:

Active transport
