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

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
