Question

Select the statement(s) that accurately describe amino acids and proteins.


Amino acids are one of four major macromolecules found in living things.


Amino acids are the building blocks of proteins.


Peptide bonds join proteins through dehydration synthesis chemical reactions.


Proteins are the building blocks of amino acids.


Peptide bonds join amino acids through dehydration synthesis chemical reactions.

Answer 1

The statements that accurately describe amino acids and proteins are:

1. **Amino acids are the building blocks of proteins.**
This statement is correct, as amino acids combine to form proteins.

2. **Peptide bonds join amino acids through dehydration synthesis chemical reactions.**
This statement is also correct. Peptide bonds are formed between amino acids via dehydration synthesis, where a water molecule is released.

The other statements are not accurate:

- **Amino acids are one of four major macromolecules found in living things.**
This is incorrect; amino acids are not a macromolecule themselves, but they are the building blocks that form the macromolecule proteins.

- **Proteins are the building blocks of amino acids.**
This is incorrect; it is the other way around—amino acids are the building blocks of proteins.
