Are vegetables comprised primarily of carbs, proteins or fat?

I'm talking about the digestive system and I want to know what enzyme breaks down vegetables. Pepsin breaks down proteins which is like meat. Gastric lipase breaks down fats which is like cheese and amylase breaks down carbs which is like bread. Where do vegetables fit in?

Veges are mainly fiber, carbohydrate, limited protein, and very limited fat, but veges have high vitamin content, if cooked properly.

Yes that's true
nutrition is the mode taking food by an organisums and its utlisation by the body.
