A molecule has been isolated from a cell. The molecule's structure has a three dimensional shape and is made of folded chains of amino acids. The function of this molecule is enzymatic catalysis of glycolysis. An analysis of this molecule would show that it contains which of these elements that would NOT be found in carbohydrates

Nitrogen.

Explanation:

Although the options for this question is not available,the major food molecules of Carbohydrate,Protein ,and Lipids all contain the elements C,H,O.

However,Nitrogen is the only elements that is present in Protein,but absent in the other food molecules.Consequently,Nitrogen is answer.

The Nitrogen forms the Amine-NH2 - of protein.

The fact that  the molecular structure has a 3-D  shape,with folded chains of amino acids,it show that  it  is protein of  tertiary structure.Although enzymes are globular proteins but of  tertiary structure.

Tertiary proteins are 3-D and the R-groups interacts with each other for distinct chemical structure
