Construct a functional pathway out of the following steps. A: Phosphorylation of $\beta$ subunits of the insulin receptor occurs. B: Insulin binds to $\alpha$ subunits of the insulin receptor.
C: PI-3K is activated.
D: IRS is phosphorylated.
A) C, A, B, D
B) B, D, A, C
C) B, A, C, D
D) B, A, D, C

Question

Quizplus · Accepted Answer

Insulin first binds to F1F1F1S1F1F1F10 subunits of the insulin receptor (B) followed by the phosphorylation of F1F1F1S1F1F1F10 subunits (A). Next, IRS is phosphorylated (D) which leads to the activation of PI-3K (C). Therefore, the correct order is B, A, D, C.
