Question

macromolecule graphic organizer
biomolecule | monomer | examples
carbohydrate | monosaccharides | • glucose • fructose • poly saccharide • lactose
lipid | fatty acids and glycerol | cholesterol steroid hormone phospholipid triglyceride
protein | | • • • •
nucleic acid | nucleotides | • • • •

Explanation:

To correct the errors in the macromolecule graphic organizer:

1. Carbohydrate Section

• Monomer: Monosaccharides (correct).
• Examples:
• Correct examples of monosaccharides: Glucose, Fructose, Galactose.
• Incorrect examples in the image: Polysaccharide (a polymer, not a monomer example) and Lactose (a disaccharide, not a monosaccharide).

2. Lipid Section

• Monomer: Lipids do not have a single universal monomer. For triglycerides (a type of lipid), the monomers are fatty acids and glycerol (the term “glycerol” was misspelled as “glycorol” in the image).
• Examples:
• Correct examples of lipids: Triglyceride, Phospholipid, Cholesterol (steroid), Steroid hormones (e.g., testosterone, estrogen).
• Note: Lipids are a diverse group; “cholesterol” and “steroid hormone” are valid, but “lipid” as a category does not have a single monomer (unlike other macromolecules).

3. Protein Section

• Monomer: Amino acids (missing in the image).
• Examples: Enzymes (e.g., amylase), Structural proteins (e.g., collagen, keratin), Transport proteins (e.g., hemoglobin), Hormones (e.g., insulin), Antibodies.

4. Nucleic Acid Section

• Monomer: Nucleotides (correct).
• Examples: DNA (deoxyribonucleic acid), RNA (ribonucleic acid), ATP (adenosine triphosphate, a nucleotide derivative).

Revised Table (Key Corrections):

Biomolecule	Monomer	Examples
Lipid	Fatty acids + Glycerol	Triglyceride, Phospholipid, Cholesterol
Protein	Amino acids	Enzyme (amylase), Collagen, Hemoglobin
Nucleic Acid	Nucleotides	DNA, RNA, ATP

of Errors:

• Carbohydrates: Polysaccharides (e.g., starch) are polymers (made of monosaccharides), and lactose is a disaccharide (two monosaccharides linked). Only monosaccharides are true monomers here.
• Lipids: The term “glycorol” is a spelling error (correct: glycerol). Lipids lack a single monomer (unlike carbs/proteins/nucleic acids), but triglycerides use fatty acids + glycerol.
• Proteins: The monomer (amino acids) was missing, and examples were not filled.
• Nucleic Acids: Examples (e.g., DNA, RNA) were missing.

This revision aligns the graphic organizer with biological principles of macromolecules, monomers, and examples.
