Question

Which of the following correctly describes the image below? (2 points)

A single hydrogen atom bonded to a central carbon atom. An amino group and a carboxylic acid group both bonded to the central carbon atom. A side chain group, represented by the variable R, is attached to the central carbon atom.

Select one:

a. Protein Molecule

b. RNA Molecule

c. Amino Acid

d. Carboxylic Acid

Answer 1

The answer would be c). amino acids

Answer 2

Answer: C

An amino acid has a central carbon atom surrounded by a hydrogen atom, a carboxyl group (-COOH) , an amino group(-NH2) and an alkyl group(-R). Hence if an a molecule has a singlt hydrogen atom which is bonded to a central carbon atom, an amino group and a carboxyl group both bonded to the same carbon atom, a R group which is also attached to the central carbon atom, the molecule is an amino acid(a monomer).
