Show Answer Key & Explanations
Step-by-step solution for: Carbs vs. Lipids
Problem Analysis:
The worksheet compares carbohydrates (Carbs) and lipids in terms of their main functions, elemental composition, monomers, and examples. Below is a step-by-step explanation and solution for each section.
---
1. Main Function:
Both carbohydrates and lipids are involved in storing energy, but they serve different roles:
- Carbohydrates: Their primary function is to provide short-term energy for the body.
- Lipids: Their primary function is to provide long-term energy storage.
So, we can fill in:
- Carbs: Short-term Energy!
- Lipids: Long-term Energy!

2. Elements that Make Up These Macromolecules:
#### Carbohydrates:
Carbohydrates are composed of three elements:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)
These elements are often represented by the general formula \( C_mH_{2m}O_m \), which shows that the ratio of hydrogen to oxygen is 2:1.
#### Lipids:
Lipids are primarily composed of:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)
However, lipids have a much lower proportion of oxygen compared to carbohydrates. They also sometimes include other elements like phosphorus (P) or nitrogen (N) in specialized forms (e.g., phospholipids).
For simplicity, we will focus on the core elements:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)

3. Monomers:
#### Carbohydrate Monomer:
The basic building block (monomer) of carbohydrates is a sugar molecule, specifically a monosaccharide. Examples of monosaccharides include glucose, fructose, and galactose.
So, we write:
- Carbohydrate Monomer: Monosaccharide
#### Lipid Monomers:
Lipids are composed of two main types of monomers:
1. Glycerol: A three-carbon alcohol.
2. Fatty Acids: Long chains of carbon and hydrogen with a carboxyl group at one end.
So, we write:
- Lipid Monomers: Glycerol & Fatty Acids
---
4. Examples of Carbohydrates and Lipids:
#### Examples of Carbohydrates:
Carbohydrates can be classified into three main groups based on their structure:
1. Monosaccharides: Simple sugars like glucose, fructose, and galactose.
2. Disaccharides: Double sugars like sucrose (table sugar), lactose (milk sugar), and maltose.
3. Polysaccharides: Complex carbohydrates like starch, glycogen, and cellulose.
Some examples:
- Glucose
- Sucrose
- Starch
- Cellulose
#### Examples of Lipids:
Lipids include a variety of molecules such as fats, oils, waxes, phospholipids, and steroids. Some examples are:
- Triglycerides (fats and oils)
- Cholesterol
- Phospholipids (found in cell membranes)
- Waxes
Some specific examples:
- Triglycerides
- Cholesterol
- Phospholipids
- Oleic acid (a fatty acid)

Final Answer:
\[
\boxed{
\begin{array}{l}
\text{Carbs: Short-term Energy!} \\
\text{Lipids: Long-term Energy!} \\
\text{Carbohydrates: C, H, O} \\
\text{Lipids: C, H, O} \\
\text{Carbohydrate Monomer: Monosaccharide} \\
\text{Lipid Monomers: Glycerol & Fatty Acids} \\
\text{Examples of Carbohydrates: Glucose, Sucrose, Starch, Cellulose} \\
\text{Examples of Lipids: Triglycerides, Cholesterol, Phospholipids, Oleic acid}
\end{array}
}
