Which of the following can be found in/on the plasma membrane? (aka cell membrane) phospholipids, cholesterol, transport protein, glycoproteins, aquaporins
Proteins which penetrate the cell membrane are called? integral proteins
Proteins which are not embedded in the cell membrane, but are loosely attached to the cell membrane surface are called? peripheral proteins
Which of the following are functions of the cell membrane proteins? transport, cell-cell recognition, attachment to cytoskeleton and collagen, cell signaling
Which of the following molecules can diffuse directly through the cell membrane, without the help of transport proteins? O2, CO2
Active transport involves which of the following? ATP, protein pumps, movement from low to high concentration
Passive transport involves which of the following? movement from high to low concentration, does not require energy, may include transport proteins
A membrane that allows some substances to go through more easily than others is called? selectively permeable
Water is able to pass through the cell membrane via? Aquaporins
The passive movement of substances from a high concentration to a low concentration without the use of transport proteins is called? Diffusion
The movement of water from HIGH concentration to LOW concentration is called? Diffusion
Movement of substances from a low concentration to a high concentration, requiring energy, is called? Active Transport
Protein pumps, like the proton pump in bacteria and mitochondria, are involved with? Active Transport
A cell has an interior concentration of 5% solutes. The cell is currently in an environment that has a concentration of 1% solutes. What is the net flow of water due to osmosis? Into the cell
A cell has an interior concentration of 3% solutes. The cell is currently in an environment that has a concentration of 10% solutes. What is the net flow of water due to osmosis? Outside of the cell
An animal cell has a solute concentration of 1.0 moles per liter. The cell is placed in distilled water. What will happen to the cell? The cell will lyse (explode)
A cell has a solute concentration of 1%. It is placed in a solution that is 5% salt. What will happen to the cell? The cell will crenate (shrink)
A solution that has more solutes than the inside of the cell is called? Hypertonic
A solution that has an equal amount solutes as the inside of the cell is called? Isotonic
A solution that has less solutes than the inside of the cell is called? Hypotonic
A series of molecular events and chemical reactions that lead to a cell's response to a signal is called? Signal Transduction Pathway
Which of the following fibers are involved with cellular movements? Microfilaments and Microtubules
Microtubules are made up of what protein unit? Tubulin
Microtubules are used in which of the following cell movements? Cilia, Centrioles/Spindle fibers, Flagella
Microfilaments are responsible for which of the following cell movements? Pseudopodia, Muscle movement, Cytoplasmic streaming
Which of the following are involved with cell structure (makes up the cytoskeleton)? Microfilaments, Intermediate filaments, Microtubules
Everything inside the cell membrane, except the nucleus, is consider part of the? Cytoplasm
What organelle makes proteins? Ribosomes
What organelle merges with the food vacuole in protists and other simple organisms and digests the food within? Lysosome
The organelle responsible for storing water in plants (but not animals) is called the? Central Vacuole
What would be the proper sequence of organelles involved with protein flow, from Ribosome to cell membrane? Ribosome -> Rough ER -> Transport Protein 1 -> Golgi -> Transport Protein 2 -> Cell Membrane

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.
