Personal Hotspot: what parts do WiFi and Cellular play?

I'm a bit confused. When I turn on Personal Hotspot on my iPhone5 what part does WiFi play (what does WiFi do to make Personal Hotspot work)? What part does the cellular connection play (what does celluar connect do to make Personal Hotspot work)?

iPhone 5, iOS 6.0.2
