Question

Correlate 2 general structural features of enzymes and how they are vital for enzymatic function.

Then, name 4 types of biological macromolecules. List a unique characteristic of each macromolecule.

Answer 1

The 2 strcuture features will be the primary amino acid sequence structure and the presence of an active site in the final structure. The active site is known as the physical space in which the substrate is being grabbed to catalyse the reaction, this is only possible because the active site has certain amino acid residues that specifically interact with the substrate's chemical groups. Such amino acid residues are there because of the primary peptide sequence in which the protein was created, without a proper primary sequence we won't have a proper active site, and without a proper active site we won0t have enzymatic activity, no substrate will be taken into reaction.

- 4 types of biological macromolecules:

1.- Proteins: Capable of catalysing biochemical reactions, the most diverse molecules in terms of number of functions

2.- Carbohydrates: Fastest source of energy

3.- Nucleic acids: Capable of forming two stranded reverse complemented interactions

4.- Lipids: Greatly hydrophobic
