Biomolecules Review worksheet - Free Printable

Let’s solve this step by step.

We are given a chart titled “BIOMOLECULES” with 4 columns. Each column has:
- Name (top box)
- Elements (middle box)
- 4 Functions (bottom section, which splits into sub-boxes — but we don’t need to fill those for now since the word bank only gives names and elements)

The Word Bank for Name & Elements includes:
LIPIDS, CHO, CHON, CARBOHYDRATES, CH0 (probably typo for CHO), PROTEINS, CHONP, NUCLEIC ACIDS

Note: “CH0” is likely meant to be “CHO” (Carbon, Hydrogen, Oxygen). We’ll treat them as same.

Now, let’s recall basic biology:

There are 4 main types of biomolecules:
1. Carbohydrates → made of C, H, O → functions: energy, structure, storage
2. Lipids → made of C, H, O (sometimes P or N, but mostly CHO) → functions: energy storage, cell membranes, insulation
3. Proteins → made of C, H, O, N (sometimes S) → so CHON → functions: enzymes, structure, transport, etc.
4. Nucleic Acids → made of C, H, O, N, P → so CHONP → functions: store genetic info, make proteins

So matching:

Column 1: Let’s say it’s CARBOHYDRATES → Elements: CHO
Column 2: LIPIDS → Elements: CHO (some sources say just CHO, even though some lipids have P, but in basic bio, it’s CHO)
Wait — but we have two “CHO” in word bank? Actually, looking again:

Word Bank:
Row 1: LIPIDS | CHO | CHON | CARBOHYDRATES
Row 2: CH0 (typo for CHO) | PROTEINS | CHONP | NUCLEIC ACIDS

So unique items:
Names: LIPIDS, CARBOHYDRATES, PROTEINS, NUCLEIC ACIDS
Elements: CHO, CHON, CHONP

But there are 4 columns → so each column gets one name and one element set.

Standard pairing:

→ Carbohydrates: CHO
→ Lipids: CHO (but sometimes listed separately — however, in many curricula, both carbs and lipids are CHO, but lipids may be noted as having more H and less O)
BUT — here we have only one “CHO” listed twice? Wait, no — actually, “CH0” is probably a typo and should be ignored or treated as CHO.

Looking at the word bank layout:

It’s arranged in a table:

| LIPIDS | CHO | CHON | CARBOHYDRATES |
|------------|--------|--------|---------------|
| CH0 | PROTEINS | CHONP | NUCLEIC ACIDS |

This seems like it’s listing all options together — not paired yet.

So total distinct names: LIPIDS, CARBOHYDRATES, PROTEINS, NUCLEIC ACIDS → 4 names → perfect for 4 columns.

Total distinct element sets: CHO, CHON, CHONP → but we need 4 element boxes.

Wait — “CH0” is likely a duplicate/typo of “CHO”. So effectively, we have:

Element options: CHO (appears twice?), CHON, CHONP

But in reality, for standard teaching:

- Carbohydrates: CHO
- Lipids: CHO (but often emphasized as high in H, low in O — still CHO)
- Proteins: CHON (plus sometimes S)
- Nucleic Acids: CHONP

So perhaps the chart expects:

Column 1: Carbohydrates → CHO
Column 2: Lipids → CHO
Column 3: Proteins → CHON
Column 4: Nucleic Acids → CHONP

That uses all 4 names and matches common curriculum.

But wait — the word bank lists “CHO” twice? Once under LIPIDS row? No — let's read carefully:

The word bank says:

“Word Bank for Name & Elements:”

Then a table:

First row: LIPIDS | CHO | CHON | CARBOHYDRATES
Second row: CH0 | PROTEINS | CHONP | NUCLEIC ACIDS

So it’s just listing all available terms — not pre-paired.

So available terms for “Name”: LIPIDS, CARBOHYDRATES, PROTEINS, NUCLEIC ACIDS
Available terms for “Elements”: CHO, CHON, CHONP, and CH0 (which we assume is CHO)

So we can use CHO twice if needed.

In most school-level charts, they assign:

- Carbohydrates: CHO
- Lipids: CHO
- Proteins: CHON
- Nucleic Acids: CHONP

Yes, that’s standard.

So now, how to arrange the 4 columns? The chart doesn’t specify order, but typically it’s:

Left to right: Carbohydrates, Lipids, Proteins, Nucleic Acids — or sometimes alphabetical, but usually by importance or frequency.

But since the problem doesn’t specify order, any order is fine as long as each name is matched with correct elements.

However, looking at the structure — the bottom part shows that under “4 Functions”, some columns split into 3 sub-boxes, others into different numbers — but since we’re only asked to fill Name and Elements (based on word bank provided), and the instruction says “Word Bank for Name & Elements”, we focus on top two rows per column.

Also, note: the “4 Functions” row might be filled later, but the word bank doesn’t provide function words, so we ignore that for now.

So final assignment:

Let’s assign columns left to right as:

Column 1: CARBOHYDRATES → Elements: CHO
Column 2: LIPIDS → Elements: CHO
Column 3: PROTEINS → Elements: CHON
Column 4: NUCLEIC ACIDS → Elements: CHONP

This uses all 4 names and the element sets appropriately.

Is there any reason to swap Carbs and Lipids? Not really — both are CHO, so either way is acceptable. But traditionally, carbohydrates come first.

Some curricula list lipids before carbs, but it doesn’t matter as long as pairs are correct.

To match common textbook order: Carbohydrates, Lipids, Proteins, Nucleic Acids.

So:

Final Answer:

Column 1 (leftmost):
Name: CARBOHYDRATES
Elements: CHO

Column 2:
Name: LIPIDS
Elements: CHO

Column 3:
Name: PROTEINS
Elements: CHON

Column 4 (rightmost):
Name: NUCLEIC ACIDS
Elements: CHONP

Note: The word bank had “CH0” which we treated as typo for “CHO”, and used “CHO” twice — which is correct because both carbs and lipids are primarily composed of Carbon, Hydrogen, and Oxygen.

Also, proteins include Nitrogen (so CHON), nucleic acids include Phosphorus (so CHONP).

This matches standard biological knowledge.

Final Answer:
From left to right, the four columns should be filled as follows:

Column 1:
Name: CARBOHYDRATES
Elements: CHO

Column 2:
Name: LIPIDS
Elements: CHO

Column 3:
Name: PROTEINS
Elements: CHON

Column 4:
Name: NUCLEIC ACIDS
Elements: CHONP
