Cellular signaling
20 important questions on Cellular signaling
What are external signals?
What are short-long distance?
- long distance signaling: hormones secreted into body fluids and binds to target cells.
Which three stages of cell signaling are there?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the function of plasmamembrane receptors?
Which plasma membrane receptors are there?
Receptor tyrosine kinases
ligand-gated ion channels
How works a G-protein-coupled receptor?
How works Receptor tyrosine kinases?
How works a ligand-gated ion channel?
Which second messengers do they have?
What is CA2+ (second messenger)?
What is inositol triphosphat (IP3)?
What is diacylglycerol (DAG)?
What types of responses are there?
What does the response "Protein synsthesis"?
What doe the response "activation of enzymes"?
What regulation has a response?
What does amplification (in response)?
What is the specifity (in response)?
- sometimes more diffrent signal molecules can give different responses ( same receptor other reponse).
What is the overall efficiencey (in response)?
What is the termination of the signal (in response)?
- unbound receptors revert to an inactive state.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
