The correct order of the macromolecules that gets digested in the body is

Options

A. Carbohydrate-fat-protein
B. Carbohydrate-protein-fat
C. Fat-protein-carbohydrate
D. Fat-carbohydrate-protein

Answer

To determine the correct order of macromolecules that get digested in the body, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Macromolecules**: The three main macromolecules that need to be digested in the body are carbohydrates, fats (lipids), and proteins.

2. **Order of Digestion**:
- **Carbohydrates**: Digestion begins with carbohydrates. The process starts in the mouth where the enzyme salivary amylase breaks down starches into simpler sugars. This digestion continues in the small intestine.
- **Fats**: The next macromolecule to be digested is fats. The digestion of fats occurs primarily in the small intestine, where bile (from the liver) emulsifies fats, and pancreatic lipase (from the pancreas) breaks them down into fatty acids and glycerol.
- **Proteins**: Lastly, proteins are digested. The digestion of proteins begins in the stomach with the enzyme pepsin and continues in the small intestine with various proteases breaking them down into amino acids.

3. **Conclusion**: The correct order of digestion of macromolecules in the body is:
- Carbohydrates → Fats → Proteins.

### Final Answer:
The correct order of macromolecules that gets digested in the body is carbohydrates, fats, and proteins.
