Which group has the same distinct class

Options

A. Sterols,Waxes, Amino acids, starch
B. Lipids,RNA,Glucine,Cellulose
C. DNA,RNA, Nucleosides, Nucleotides
D. Ribose, Surose, Glucose, Maltose

Answer

To determine which group has the same distinct class, we need to analyze the options provided and identify the common classification of the molecules in each group.

### Step-by-Step Solution:

1. **Analyze the First Option: Sterol, Waxes, Amino Acid, and Starch**
- **Sterols** and **waxes** are types of lipids.
- **Amino acids** are the building blocks of proteins.
- **Starch** is a carbohydrate.
- Since these belong to different classes (lipids, proteins, carbohydrates), this option is incorrect.

2. **Analyze the Second Option: Lipids, RNA, Glucose, and Cellulose**
- **Lipids** are a distinct class of biomolecules.
- **RNA** is a nucleic acid.
- **Glucose** is a monosaccharide (carbohydrate).
- **Cellulose** is a polysaccharide (carbohydrate).
- Since these belong to different classes (lipids, nucleic acids, carbohydrates), this option is also incorrect.

3. **Analyze the Third Option: DNA, RNA, Nucleoside, and Nucleotides**
- **DNA** and **RNA** are both nucleic acids.
- **Nucleosides** are components of nucleotides (which are also part of nucleic acids).
- Although nucleosides and nucleotides are related to nucleic acids, they are not all the same distinct class as they represent different components. Thus, this option is incorrect.

4. **Analyze the Fourth Option: Ribose, Sucrose, Glucose, and Maltose**
- **Ribose** is a monosaccharide (specifically a pentose sugar).
- **Sucrose** is a disaccharide made from glucose and fructose.
- **Glucose** is a monosaccharide.
- **Maltose** is a disaccharide formed from two glucose molecules.
- All four of these molecules are carbohydrates. Therefore, this option is correct.

### Conclusion:
The correct answer is **Option 4: Ribose, Sucrose, Glucose, and Maltose** as they all belong to the class of carbohydrates.
