Which of the following cannot be hydrolysed further: glucose, fructose, sucrose, ribose ?

Explanation

To determine which of the following cannot be hydrolyzed further: glucose, fructose, sucrose, or ribose, we need to understand the classification of these carbohydrates.

### Step 1: Identify the types of carbohydrates
- Carbohydrates are classified into monosaccharides, disaccharides, and polysaccharides.
- Monosaccharides are the simplest form of carbohydrates and cannot be hydrolyzed further.
- Disaccharides consist of two monosaccharide units and can be hydrolyzed into their constituent monosaccharides.
