You are given four test tubes containing purified biological 1 point
macromolecules. The test tubes are unlabeled except for a number
between 1 and 4. You are told that one test tube contains a protein, one
contains a lipid, one contains a carbohydrate, and one contains a nucleic
acid. You then perform some tests on the macromolecules and collect the
following information: 1) Test tubes #2 and #4 contain nitrogen, but the
other tubes do not. 2) The contents of test tube #3 are not soluble in water,
but the contents of the other test tubes are soluble in water. 3)The
contents of test tube #1 can be broken down into subunits that are all
exactly identical to each other. 4) The macromolecule in test tube #2 is
found to have a globular shape. What are the identities of the
macromolecules present in test tubes #2*
O Carbohydrate
Protein

Lipid
Nucleic Acid
