Question

reviewing structure of macros
draw a line from each structure below to its appropriate macromolecule

1. carbohydrate
2. lipid
3. protein
4. nucleic acid

Explanation:

Step1: Identify Carbohydrate Structure

Carbohydrates are made of monosaccharides (simple sugars) linked together. The middle - top structure with hexagonal sugar rings (monosaccharides linked) is a carbohydrate. So, draw a line from "1. CARBOHYDRATE" to the structure with linked hexagonal sugar rings (the second structure on the right).

Step2: Identify Lipid Structure

Lipids (like triglycerides) have a glycerol and fatty acid chains. The bottom - right structure with long hydrocarbon chains and glycerol - like groups is a lipid. So, draw a line from "2. LIPID" to the bottom - right structure (the fourth structure on the right).

Step3: Identify Protein Structure

Proteins are made of amino acids linked by peptide bonds. The top - right structure with amino acid - like groups (with N, C, O, H and peptide bonds) is a protein. So, draw a line from "3. PROTEIN" to the top - right structure (the first structure on the right).

Step4: Identify Nucleic Acid Structure

Nucleic acids (like DNA/RNA) have a phosphate group, sugar, and nitrogenous base. The third structure on the right (with phosphate, sugar, and nitrogenous base labeled) is a nucleic acid. So, draw a line from "4. NUCLEIC ACID" to the third structure on the right.

Answer:

1. CARBOHYDRATE - linked hexagonal sugar rings structure (second right structure)
2. LIPID - bottom - right long - chain structure (fourth right structure)
3. PROTEIN - top - right amino - acid - like structure (first right structure)
4. NUCLEIC ACID - structure with phosphate, sugar, base (third right structure)
