What biological macromolecule is made up of monomers like the one shown below? a molecule with the formula c6h12o6. five carbon atoms and one oxygen atom form a hexagonal ring, with the other atoms bonded to that ring.

The biological macro molecule is CARBOHYDRATE.
Carbohydrates are made up of just three elements, which are carbon, hydrogen and oxygen, all joined together in a ringed structure. The number of carbon a carbohydrate has determined the class of carbohydrate under which it is grouped. The particular one we are given in this question has five carbon, so it is a pentose sugar.
Carbohydrate are the major source of energy in the living cells.

Life, yes life it self madden
