Membrane Trans FHS

Membrane Transport

QuestionAnswer
What is the main function of the plasma membrane maintain homeostasis through its selective permeability
define concentration gradient Differences in concentration between two adjacent areas
Movement from areas of high concentration to low concentration passive - requires no energy
Movement from areas of low concentration to high concentration active - working against the gradient
Direction of movement depends on the concentration gradient and will continue until ___________ is reached. equilibrium
define diffusion movement of solute particles from an area of [high] to [low]
define facilitated diffusion transport proteins facilitate the movement of molecules from an area of [high] to [low]
define osmosis diffusion of water across a selectively permeable membrane from an area of [high] to [low]
diffusion, facilitate diffusion, and osmosis are examples of passive transport
define hypotonic relative to the cell there is a lower concentration of solute and a higher [H2O]
define isotonic equal [solute] when compared to the cell
define hypertonic relative to the cell there is a higher concentration of dissolved solute and a lower [H2O]
define active transport against the concentration gradient / therefore requires energy (ATP)
give 2 examples of active transport endocytosis, exocytosis
process by which cells absorb molecules (such as proteins) by engulfing them endocytosis
durable process by which a cell directs the contents of secretory vesicles out of the cell membrane and into the extracellular space exocytosis

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
