This worksheet helps students categorize the four major biological macromolecules by matching their chemical elements, specific types, and biological functions.

You're working with a biomolecule matching chart. The goal is to correctly assign the Elements, Types, and Functions to each of the four major biomolecules: Carbohydrates, Lipids, Proteins, and Nucleic Acids.

Let’s solve this step by step using biological knowledge and match the correct terms from the bottom bank into the table.

## ✔ Step 1: Understand the Biomolecules

1. Carbohydrates

- Elements: C, H, O → CHO
- Types: Sugars, starches (e.g., glucose, cellulose, glycogen)
- Function: Primary source of short-term energy

2. Lipids

- Elements: C, H, O (sometimes P) → mostly CHO, but some have P (like phospholipids), so CHONP can be used for complex lipids — however, in basic biology, lipids are often listed as CHO.
- But looking at the options, “CHO” is used for carbohydrates, and “CHON” for proteins — so lipids = CHO is acceptable here for simple fats/oils.
- Types: Fats, oils, waxes, steroids
- Function: Long-term energy storage, insulation, repel water, hormones (steroids)

3. Proteins

- Elements: C, H, O, N → CHON
- Types: Enzymes, antibodies, receptors, muscle fibers
- Function: Movement (muscle), defense (antibodies), communication (receptors/hormones)

4. Nucleic Acids

- Elements: C, H, O, N, P → CHONP
- Types: DNA, RNA — which store genetic info → genes
- Function: Store and transport genetic information

## ✔ Step 2: Match the Bottom Bank to the Table

The bottom section has boxes with terms we need to drag or assign to the correct row/column.

Let’s organize them:

Elements Column:

- Carbohydrates → CHO
- Lipids → CHO (simplified; though some have P, CHO is standard for basic level)
- Proteins → CHON
- Nucleic Acids → CHONP

> ⚠️ Note: There’s a conflict — both Carbs and Lipids are CHO. That’s correct biologically. Some curricula distinguish lipids as CHONP if including phospholipids, but here, since “CHONP” is only listed once and assigned to nucleic acids, and “CHO” appears twice — it’s fine. Lipids are mostly CHO.

Types Column:

- Carbohydrates → sugars, starches
- Lipids → fats, oils, waxes, steroids
- Proteins → muscle, antibodies, receptors (these are examples of protein types/functions)
- Nucleic Acids → genes

Function Column:

- Carbohydrates → Short-term energy
- Lipids → long-term energy, Repel water, Hormones, Insulation
- Proteins → Movement, Defense, Communicate
- Nucleic Acids → Store and transport genetic information

## ✔ Final Completed Table:

| Biomolecules | Elements | Types | Function |
|------------------|----------|------------------------|-----------------------------------------|
| Carbohydrates | CHO | sugars, starches | Short-term energy |
| Lipids | CHO | fats, oils, waxes, steroids | long-term energy, Repel water, Hormones, Insulation |
| Proteins | CHON | muscle, antibodies, receptors | Movement, Defense, Communicate |
| Nucleic Acids | CHONP | genes | Store and transport genetic information |

## 🧠 Explanation Summary:

- Carbohydrates are made of carbon, hydrogen, oxygen (CHO), include sugars and starches, and provide quick energy.
- Lipids also mainly contain CHO, include fats/oils/waxes/steroids, and serve as long-term energy, waterproofing, insulation, and hormone precursors.
- Proteins contain CHON, include structural and functional molecules like muscle, antibodies, and receptors, and perform movement, defense, and cell communication.
- Nucleic Acids contain CHONP, are made of genes (DNA/RNA), and their main job is storing and transmitting genetic information.

✔ This matches all the pieces logically and scientifically!
