Chapter 11: Cell Signaling Flashcards
1
Q
What is cell communication
A
Cell can signal other cell and interpret signal molecules from other cells and environment.
2
Q
Four types of cell communication
A
- Autocrine
- Paracrine
- Gap junctions
- Endocrine
3
Q
What is the signaling molecule
A
Signaling cell can send extracellular message to the receptor.
4
Q
Three stages of cell signaling
A
- Reception
- Transduction
- Response
5
Q
Is cell communication a multistep or not?
A
Yes
6
Q
Where does reception happen
A
In extracellular fluid
7
Q
Where do transduction and response happen
A
In cytoplasm
8
Q
Apoptosis vs Necrosis
A
- Necrosis: Increase in cell volume, Plasma membrane lose, leakage of cellular contents.
- Apoptosis: Cell shrink, Plasma membrane blebbing, NO leakage.
