Find the incorrect w.r.t. breakdown of biomolecules under the influence of succus entericus.

Options

A. Maltose `overset("Maltase")(to)` Glucose + Glucose
B. Sucrose `overset("Invertase")(to)` Glucose + Fructose
C. Lactose `overset("Lactase")(to)` Maltose + Galactose
D. Isomaltose `overset("Isomaltae")(to)` Glucose + Glucose

Answer

To solve the question, we need to identify the incorrect statement regarding the breakdown of biomolecules under the influence of succus entericus (intestinal juice). Let's break down the process step by step.

### Step 1: Understand Succus Entericus
Succus entericus is the intestinal juice secreted by the intestinal glands. It contains various enzymes that aid in the digestion of carbohydrates, proteins, and fats.

### Step 2: Identify the Enzymes Present
The main enzymes present in succus entericus include:
- **Maltase**: Breaks down maltose into two glucose molecules.
- **Sucrase (Invertase)**: Breaks down sucrose into glucose and fructose.
- **Lactase**: Breaks down lactose into glucose and galactose.
- **Isomaltase**: Breaks down isomaltose into two glucose molecules.

### Step 3: Analyze the Breakdown of Each Biomolecule
1. **Maltose**:
- Enzyme: Maltase
- Breakdown: Maltose → Glucose + Glucose (Correct)

2. **Sucrose**:
- Enzyme: Sucrase (Invertase)
- Breakdown: Sucrose → Glucose + Fructose (Correct)

3. **Lactose**:
- Enzyme: Lactase
- Breakdown: Lactose → Glucose + Galactose (Correct)

4. **Isomaltose**:
- Enzyme: Isomaltase
- Breakdown: Isomaltose → Glucose + Glucose (Correct)

### Step 4: Identify the Incorrect Statement
In the video transcript, it was mentioned that lactose breaks down into glucose and lactose, which is incorrect. The correct breakdown of lactose is into glucose and galactose.

### Conclusion
The incorrect statement regarding the breakdown of biomolecules under the influence of succus entericus is that lactose breaks down into glucose and lactose. The correct breakdown is glucose and galactose.

### Final Answer
The incorrect statement is: "From the breakdown of lactose, we get glucose and lactose."
