Cell Communication

QuestionAnswer
What is a signal-transduction pathway? a series of steps by which a signal on a cell's surface is converted into a specific cellular response
what other types of signaling? - local regulators are messenger molecules that travel only short distances - In long-distance signaling, plants and animals use chemicals called hormones
What are the 3 processes that cells receiving signals go through? - Reception - Transduction - Response
what is reception? a signal molecule binds to a receptor protein, causing it to change shape
What are intracellular receptors? found in cytosol or nucleus of target cells
what are the 3 main types of membrane receptors? - G protein linked receptors - Receptor tyrosine Kinases - Ion channel receptors
What are G protein linked receptors? - plasma membrane receptor that works with help of a G protein - G protein acts as an on/off switch, if GDP is bound to the G protein then it is inactive
What are tyrosine Kinase? - membrane receptors that attach phosphates to tyrosines - can trigger multiple signal transduction pathways at once
What are Ion channel receptor? - acts as a gate when the receptor changes shape - when a signal molecule binds as a ligand to the receptor the gate allows specific ions, such as Na + or Ca+ to go through
What are the molecules that relay a signal from receptor to response? Proteins
In many pathways the signal is transmitted by a cascade of protein called? phosphorylations
what do phosphate enzymes do? they reverse the phosphorylation and remove the phosphate
what are second messengers? small, non protein, water soluble molecules or ions

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.
