Question
1)
When insulin binds the insulin receptor, the IRS protein:
phosphorylates the insulin receptor
binds to the phosphorylated beta-chains of the insulin receptor
binds the G-alpha subunit
is not recruited to the receptor complex until Grb2 is associated
2)
Elevated levels of orotic acid can be clinically diagnostic for defects in which of the following pathways?
DNA replication
purine synthesis
purine salvage
pyrimidine synthesis
phosphorylates the insulin receptor
binds to the phosphorylated beta-chains of the insulin receptor
binds the G-alpha subunit
is not recruited to the receptor complex until Grb2 is associated
Explanation / Answer
1) binds to the phosphorylated beta-chains of the insulin receptor
2) pyrimidine synthesis
