14 how many atoms of each type in the molecule h₂co₃?
h ____ c __ o ____

1. macromolecules are large molecules (polymers) built of smaller units, called ______
2. fill in the following chart:

macromolecule	monomers	function(s)	elements contained	example
lipids
proteins
nucleic acids

1. look at the following pictures/diagrams. which type of macromolecule is represented in by each picture?

(images: amino acids chain, glucose structure, unsaturated fatty acid structure, nucleotide structure)

Explanation:

Question 14

Step1: Analyze H atoms

In the formula \( \text{H}_2\text{CO}_3 \), the subscript of H is 2, so there are 2 H atoms.

Step2: Analyze C atoms

The subscript of C is 1 (implied if no subscript), so there is 1 C atom.

Step3: Analyze O atoms

The subscript of O is 3, so there are 3 O atoms.

Macromolecules (polymers) are made of smaller repeating units called monomers. This is a key concept in biochemistry, where polymers like carbohydrates, proteins, etc., are synthesized from monomeric units.

• Carbohydrate: Monomers are monosaccharides (e.g., glucose). Functions include energy source, structural support (e.g., cellulose in plants). Elements: C, H, O. Example: starch.
• Lipids: Monomers are fatty acids and glycerol. Functions: energy storage, insulation, cell membrane structure. Elements: C, H, O (sometimes P). Example: triglycerides.
• Proteins: Monomers are amino acids. Functions: structural (e.g., collagen), enzymatic, transport (e.g., hemoglobin). Elements: C, H, O, N (sometimes S). Example: insulin.
• Nucleic Acids: Monomers are nucleotides. Functions: store and transmit genetic information. Elements: C, H, O, N, P. Example: DNA.

Answer:

H: 2, C: 1, O: 3
