This is a tough one!
Shown is the biosynthetic cyclization of oxidosqualene catalyzed by oxidosqualene cyclase (OSC) leading to lanosterol as the final product.
The reaction starts with a protononation step as shown. Indicate the flow of electrons after the initial protonation step leading to the product given.
Indicate the flow of electrons by starting your curved arrow at a bond or unshared electron pair.
In this question, the endpoint of your curved arrow will be an atom.
You should be able to find appropriate hot spots in the drawing.
