Explanation:

To fill the chart, we use knowledge of biological macromolecules:

Carbohydrates:

• Monomers: Monosaccharides (e.g., glucose, fructose).
• Polymers: Polysaccharides (e.g., starch, glycogen, cellulose).
• Function 1: Primary energy source for cells.
• Function 2: Structural support (e.g., cellulose in plant cell walls).
• Examples: Glucose, starch, glycogen, cellulose.

Lipids:

• Monomers: Fatty acids and glycerol (for triglycerides; some lipids like steroids have no true monomers).
• Polymers: Triglycerides, phospholipids, steroids (lipids are not true polymers but are grouped here).
• Function 1: Long - term energy storage.
• Function 2: Structural component of cell membranes (phospholipids).
• Function 3: Insulation and protection (e.g., fat in animals).
• Examples: Fats, oils, phospholipids, cholesterol.

Proteins:

• Monomers: Amino acids.
• Polymers: Polypeptides (folded into functional proteins).
• Function 1: Enzymatic catalysis (e.g., amylase).
• Function 2: Structural support (e.g., collagen).
• Function 3: Transport (e.g., hemoglobin).
• Function 4: Defense (e.g., antibodies).
• Function 5: Regulation (e.g., hormones like insulin).
• Examples: Hemoglobin, insulin, collagen, enzymes like lactase.

Now we can fill the chart:

	Monomers	Polymers	Function 1	Function 2	Function 3	Function 4	Function 5	Examples
Lipids	Fatty acids, glycerol	Triglycerides, phospholipids, steroids	Long - term energy storage	Structural component of cell membranes	Insulation/protection	-	-	Fats, oils, phospholipids, cholesterol
Proteins	Amino acids	Polypeptides	Enzymatic catalysis	Structural support	Transport	Defense	Regulation	Hemoglobin, insulin, collagen, lactase
