Chapter 4 Slandis

Active and passive transportation

QuestionAnswer
What happens when a cell is placed in hypotonic solution? The water will move into the cell causing the cell to swell and maybe burst.
What is the main difference between Active and Passive Transport? Passive Transport moves the molecule down towards the cell concentration gradient and Active Transport moves the molecules against the cell concentration gradient.
Whats an example of Active Transport? Sodium-Potassium pump
The process that moves molecules from an area of high concentration to an area of low concentration that requires no energy is? Diffusion
What happens when a cell is placed in a hypertonic solution? The water will leave the cell causing the cell to shrink and shrivel.
To keep cells intact they need to be placed in... isotonic solution
what are Ion Channel Proteins? They move the proteins across the plasma membrane.
moves sodium out of the cell and potassium into the cell, both against there concentration gradients. Sodium-Potassium Pump
Moves large molecules outside of the cell. Exocytosis
Process in which take in large molecules by vesicle formation Endocytosis
moves large substances, even another cell, into the cell. phagocytosis
involves the movement of liquid or other particles into the cell. pinocytosis
What are some examples of Passive Transport? Diffusion, Ion Channels, Facilitated Diffusion, Osmosis
What are some examples of Active Transport? Sodium-Potassium Pump

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.
