Chapter 7: 7.4 Signalling Response Flashcards
1
Q
What are the types of signalling responses?
A
- Gene expression
- Metabolism
- Apoptosis
2
Q
Cellular responses:
Gene expression
A
Final enzyme could be gene expression regulatory protein
* Can transform environmental signals to changes in gene expression
3
Q
Cellular responses:
Metabolism
A
Final protein could targe metabolic enzymes that are activated based on certain types of signals
* Growth and development
4
Q
Cellular responses:
Apoptosis
A
Programmed cell death when conditions are not good or cell has sustained damage
5
Q
Apoptosis:
What is apoptosis?
A
Process of programmed cell death
6
Q
Apoptosis:
Why do cells undergo apoptosis?
A
Cells that are perceived as damaging choose to undergo cell death
* Dividing leads to diseases like cancer
7
Q
Apoptosis:
What is the:
* Signal?
* Receptor?
* Response?
A
- Signal: Often DNA Damage
- Receptor: DNA Polymerase and other types of DNA binding proteins
- Response: Dissolve and degrade cellular components
