Question

using the table, which class of biomolecule is represented by the diagram beneath it?
a has glycerol as a building block.
b contains both acid groups and amino groups.
c formed from subunits containing a nitrogenous base, a phosphate, and ribose.
d includes sugar and starches.
class a
class c
class b
class d

Explanation:

The diagram shows an amino acid structure. Amino acids are the building blocks of proteins. Proteins are formed from subunits (amino acids) that contain both amino (\(-NH_2\)) and acid (\(-COOH\)) groups. Class B in the table (assuming the table's characteristics match protein - related ones, as the key characteristic here is the presence of amino and acid groups which are typical for amino acids/proteins) would be the correct classification.

Answer:

Class B
