QuestionAnswer
receptor tyrosine kinase (RTK) Coordinate complex growth decisions, Minutes to hours
G-Protein coupling receptor (GCPR) Amplify a signal widely, Seconds to minutes
ion gated channel Change electrical signaling, Milliseconds
second messengers A molecule that relays messages in a cell from a receptor to a target where an action within the cell takes place.
Water-soluble molecules plasma membrane receptors
Small/non-polar intracellular receptors
paracrine signaling a signaling cell acts on nearby target cells by secreting molecules of a local regulator
endocrine signaling Specialized cells release hormones, which travel through the circulatory system to other parts of the body, where they reach target cells that can recognize and respond to them. Hormonal signaling in animals.
photophosphorylation The process of generating ATP from ADP and phosphate by means of chemiosmosis, using a proton-motive force generated across the thylakoid membrane of the chloroplast or the membrane of certain prokaryotes during the light reactions of photosynthesis.
direct signaling occurs when cells are in physical contact, either through gap junctions or other forms of direct cell-to-cell recognition
autocrine signaling involves a cell releasing a signal that binds to receptors on itself
endocrine signaling signaling uses hormones to send signals over long distances through the bloodstream
paracrine signaling a signaling cell acts on nearby target cells by secreting molecules of a local regulator
synaptic signaling A nerve cell releases neurotransmitter molecules into a synapse, stimulating the target cell, such as a muscle or nerve cell. In the animal nervous system.

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.
