Review carefully the structure of ATP. In addition to being the "energy currency" for the cell, ATP is a monomer for which macromolecule?

Question 3 options:

a	Lipid
b	DNA
c	Protein
d	Carbohydrate
e	RNA

Answer 1

ATP consists of adenosine and consequently, a monomer of RNA.

Answer 2

So we want to know which of the macromolecules is made of ATP (in imprecise layman's terms)

First I think it is important to remove choices that make no sense.

Lipids and carbs don't remotely have the structure of ATP within them. (I'm being hand wavy here)

Proteins consist of long chains of amino acids which isn't anything remote to the ATP molecule

However, DNA and RNA both have one monomer who's synthesis requires ATP which is tricky. Also look at their structure. They look roughly similar so we know we are on the right track. However, if you refer to your textbook you probably will find that ATP must be converted to dATP before being used to synthesize DNA. The question is specifically asking for ATP.

So there we have it.

ATP is the monomer for the synthesis of RNA. ka-ching
