QuestionAnswer
What is Tight Junction and its function? Tight junctions are specialized structures that link adjacent epithelial cells. They prevent substances from moving through the spaces between cells.They define different functional regions of the membrane by restricting the migration materials from one r
What is the difference and similarities of all the junctions? They all the junctions besides tight junction aid in cell connection.Both Desmosomes and Tight junctions are found in animal cells as well as Gap Junction. Tight Junction and Desmosomes have similar structures.
What is cell adhesion and recognition? Cell adhesion is when one cell specifically binds to another cell of a certain type. Cell recogniton is when the connection between the two cells is strengthened
Relationship between Selective permeability, Active Transport, and Passive Transport.... Active and Passive transport are types of selective permeability. One requires energy, because it goes against the concentration gradient being active transport. Passive transport is the complete opposite.
Difference between Facilitated and Simple Diffusion.... Facilitated diffusion is a passive transport for spcific types of protiens. Simple diffusion puts protiens were its going to balance out inside and outside.
What is Osmosis? Osmosis is diffusion with only water involved.
Relationship(s) between isotonic, hypotonic, and hypertonic.... Hypotonic is when there is more solution then solute. Hypertonic is when there is more solute then solution. *Water always moves to the hypertonic. Isotonic is when both solution and solute is evened out.
What are uniports, symports, and antiports???? Uniports are active transports that take in one (1) specific type of protien in one direction. Symport takes two (2) specific proteins in the same direction. Antiport is similar to symport except it takes the two (2) specific protiens in different direect
Two(2)Basic types of active transports? Primary active transport requires the direct participation of the energy-rich molecule ATP. Secondary active transport does not use ATP directly; rather, its energy is supplied by an ion concentration gradient established by primary active transport.
Three (3) types of endocytosis.... Phagocytosis, Pincocytosis, Receptor-mediated Endocytosis
How does receptor mediated endocytosis work?? Receptor-mediated endocytosis is used by animal cells to capture specific macromolecules from the cell's environment. This process depends on receptor proteins, integral membrane proteins that can bind to a specific molecule in the cell's environment.

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.
