Answer:
1. Insulin binds to the alpha subunit of the insulin receptor
2. Insulin receptor tyrosine kinase is activated
3. IRS proteins are phosphorylated
4. PDK1, a PIP3-dependent protein kinase, is activated
5. Phosphinositide 3-kinase (PI-3K) is phosphorylated
6. PIP2 is converted to PIP3
7. Akt is activated
8. Glut4 receptors are moved to the cell membrane
The correct choice is option c, which identifies Ras.
