L48. Molecular Basis of Disease

Question 1

Name the 3 types of membrane receptors.

Answer 1

G protein coupled receptors
enzyme linked receptors (involves RTKs)
Ion channel receptors

Question 2

Give an example of a final target molecule and the consequences of it.

In cellular responses, the final target molecule can be a transcription factor (protein which binds to DNA to regulate gene transcription).

Question 3

Give the main issue behind :
Type 1 diabetes - 
Type 2 diabetes
Multiple Sclerosis - 
Periodontitis -

Answer 3

Type 1 diabetes - loss of signal
Type 2 diabetes - target ignores the signal
Multiple Sclerosis - signal doesn’t reach the target
Periodontitis - overexpression (bone resorption by osteoclasts)
