Topic 7 Cell Communications Flashcards
1
Q
What are the 4 reasons cell communication is essential?
A
Embryo patterning, coordination among cells, motility, environmental sensing
2
Q
What is paracrine signaling?
A
local signaling, cell released signal molecule and adjacent cells detect it
3
Q
What is synaptic signaling?
A
4
Q
What is endocrine (hormonal) signaling?
A
Distance signaling, gland releases hormone in blood and travels to the necessary cells
5
Q
What are the 3 stages of genetic signaling pathway?
A
Reception, transduction, response
6
Q
What happens during reception?
A
receptor protein detects signaling molecule at cell membrane
7
Q
What happens during transduction?
A
Proteins pass the signal to where the response needs to come from
8
Q
What happens during response?
A
The cells response to the signal
