Membrane Transport

QuestionAnswer
solutes Substances (solid, liquid, or gas) in a solution. The lesser amount
Solvents substances found in the greater amount
Solutions Contain a solvent and the solute
Diffusion means that the substance moves across the membrane from high to low
Concentration Gradiant the movement of molecules from high to low
Osmosis The diffusion of water across a membrane through channels called aquaporins
Isotonic Stays the same
Selectivly Permeable membranes that select what can and cant enter due to the nature of their composistion
Passive Methods The movement of the substance across the membrane is passive, no energy required
Active Methods the movement of the substance across the membrane is active, energy or ATP is required.
Membrane Transport how membranes move substances into the cell
Plasma Membrane cell membranes are composed of organic molecules called phospholipids
A cell with a higher solute concentration than the solution in which it is placed will do what GAIN WATER
A CELL WITH THE SAME SOLUTE CONCENTRATION AS ITS ENVIRONMENT WILL EXPERIENCE WHAT NO NET MOVEMENT OF WATER INTO OR OUT OF THE CELL
IN ORDER TO REHYDRATE THE EYES, EYEDROPS SHOULD BE WHAT IN RELATION TO THE SALINE OF THEY EYES HYPOTONIC
A PATIENT IS RECEIVING A DRIP OF 5% DEXTROSE. AT THIS RATE THE CONCENTRATION OF DEXTROSE IS ISOTONIC TO THE BLOODSTREAM. IF WE INCREASE THE CONCENTRATION OF DEXTROSE THEN THE DEXTROSE BECOMES WHAT TO THE BLOODSTREAM HYPERTONIC
IF YOU WERE TO DRINK SEA WATER AS OPPOSED TO TAP WATER, YOU WOULD EXPECT YOUR BODYS CELLS TO LOSE WATER TO EQUALIZE CONCENTRATION
TYPE OF PASSIVE TRANSPORT INVOLVING THE USE OF PROTEIN CHANNEL FACILITATED DIFFUSION
TYPE OF TRANSPORT REQUIRING THE USE OF ENERGY ACTIVE TRANSPORT
PASSIVE TRANSPORT TYPE INVOLVING MOVEMENT THROUGH THE PHOSPHOLIPID BYLAYER DIFFUSION
TYPE OF TRANSPORT REQUIRING THE USE OF A PROTEIN PUMP TO MOVE SUBSTANCES AGAINST THE CONCENTRATION GRADIENT

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.
