Which of the following is NOT directly dependent on a person's adequate protein intake?

Options

A. Formation of enzymes
B. Formation of glycogen stores in the liver
C. Production of antibodies in the immune system
D. Production of muscle tissue.

Answer

To solve the question "Which of the following is NOT directly dependent on a person's adequate protein intake?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Role of Proteins**:
- Proteins are essential macromolecules that play a critical role in various bodily functions, including the formation of enzymes, antibodies, and muscle tissues.

2. **Analyze Each Option**:
- **Option 1: Formation of Enzymes**:
- Enzymes are proteins that catalyze biochemical reactions. Therefore, their formation is directly dependent on adequate protein intake.
- **Option 2: Formation of Glycogen in the Liver**:
- Glycogen is a polysaccharide made from glucose units. The synthesis of glycogen does not directly rely on protein intake, as it primarily depends on carbohydrate intake. Thus, this option is likely the correct answer.
- **Option 3: Production of Antibodies in the Immune System**:
- Antibodies are proteins produced by the immune system to fight infections. Their production is directly dependent on adequate protein intake.
- **Option 4: Production of Muscle Tissues**:
- Muscle tissues are made up of proteins, and their production is directly dependent on protein intake.

3. **Conclusion**:
- After analyzing all options, Option 2 (Formation of Glycogen in the Liver) is the only one that is NOT directly dependent on a person's adequate protein intake.

### Final Answer:
**Option 2: Formation of Glycogen in the Liver**
