What is the prepositional phrase in the following sentence and what is the object of the preposition?

Question

Fats release energy slowly, instead of the quick release from carbohydrates.
I know that instead of is the preposition. Is EVERYTHING behind it the prepositional phrase and if so, what is the object of the preposition?

Answer 1

You have two prepositional phrases.

You found the first: instead of the quick release.

The other phrase: from carbohydrates.

Answer 2

preposition = bold
object of preposition = underlined

instead of the quick release from carbohydrates

Answer 3

Thank you for the quick response! So, is release the object or quick release? For the second one, the object would obviously be carbohydrates.

Answer 4

Only "release." Adjectives are not objects of anything, and "quick" is an adjective.
