Question

you have not yet completed this question. at least one additional response is required. chapter 3: chemistry of life: breaking good page(s) 47-50 3.3. describe the structure and function of the four major classes of biomolecules and their roles in biological systems. complete the following passage. the biomolecules known as ◌◌◌◌ are the most numerous and versatile category of biomolecules. these complex ◌◌◌◌ are constructed of different combinations of 20 ◌◌◌◌ that allow them to vary in size and shape. these combinations are the foundation of the ◌◌◌◌ structural levels of these molecules. options: four, nucleic acids, two, polymers, amino acids, proteins

Explanation:

1. The first blank: Proteins are the most numerous and versatile biomolecules. So we choose "proteins".
2. The second blank: Proteins are complex polymers (polymers are large molecules made of repeating subunits). So we choose "polymers".
3. The third blank: Proteins are made of 20 different amino acids. So we choose "amino acids".
4. The fourth blank: Proteins have four structural levels (primary, secondary, tertiary, quaternary). So we choose "four".

Answer:

The biomolecules known as $\boldsymbol{\text{proteins}}$ are the most numerous and versatile category of biomolecules. These complex $\boldsymbol{\text{polymers}}$ are constructed of different combinations of 20 $\boldsymbol{\text{amino acids}}$ that allow them to vary in size and shape. These combinations are the foundation of the $\boldsymbol{\text{four}}$ structural levels of these molecules.
