Which one of the following is wrongly matched?

Options

A. Red muscle - Myoglobin
B. Troponin - Protein of mysosin filament
C. Tendon - Connective tissue
D. Myosin - contractile protein

Answer

To determine which of the following options is wrongly matched, we need to analyze each pairing provided in the question:

1. **Red Muscle to Myoglobin**
2. **Troponin to the Protein of the Myosin Filament**
3. **Tendon to Connective Tissue**
4. **Myosin to Contractile Protein**

Now, let's evaluate each option step by step:

### Step 1: Analyze "Red Muscle to Myoglobin"
- Red muscles contain a pigment called myoglobin, which is an oxygen-binding protein. This is a correct pairing.

**Hint:** Remember that red muscles are rich in myoglobin, which helps in oxygen storage.

### Step 2: Analyze "Troponin to the Protein of the Myosin Filament"
- Troponin is actually associated with actin, not myosin. It plays a role in regulating muscle contraction by masking the binding sites on actin. Therefore, this pairing is incorrect.

**Hint:** Troponin is related to actin, not myosin; think about its role in muscle contraction.

### Step 3: Analyze "Tendon to Connective Tissue"
- Tendons are indeed a type of dense connective tissue that connects muscles to bones. This is a correct pairing.

**Hint:** Tendons are the structures that link muscles to bones.

### Step 4: Analyze "Myosin to Contractile Protein"
- Myosin is one of the main contractile proteins found in muscle fibers, along with actin. This is a correct pairing.

**Hint:** Myosin is a key player in muscle contraction, working alongside actin.

### Conclusion:
After analyzing all the options, the wrongly matched pair is **"Troponin to the Protein of the Myosin Filament."** Troponin is associated with actin, not myosin.

### Final Answer:
The wrongly matched option is **Troponin to the Protein of the Myosin Filament.**
