Place these steps of the insulin signaling pathway in the correct order from insultin is secreted to glucose enters the cell. Place all eight steps. The abbreviation PIP2 is used for phosphatidylinositol 4,5-bisphosphate; PIP3 is used for phosphatidylinositol 3,4,5-trisphosphate.
1. Activation of Akt
2. Binding of insulin to the alpha subunit of the insulin receptor
3. Phosphorylation of IRS proteins
4. Conversion of PIP2 to PIP3
5. Glut4 receptors transported to cell membrane
6. Phosphorylation of phosphinositide 3-kinase (PI-3K)
7. Activation of PIP3-dependent protein kinase B (PDK1)
8. Activation of insulin receptor tyrosine kinase
