The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the location of ATPase in muscle tissue. ATPase is an enzyme that catalyzes the hydrolysis of ATP, releasing energy. 2. **Identifying the Muscle Components**: In muscle tissue, the main proteins involved in contraction are myosin and actin. Myosin is a thick filament, while actin is a thin filament. 3. **Focusing on Myosin**: The myosin molecule has a globular head that acts as an ATPase. This head is responsible for binding ATP and hydrolyzing it to ADP and inorganic phosphate, which provides the energy needed for muscle contraction. 4. **Distinguishing Between Proteins**: Other proteins such as actin, troponin, and tropomyosin do not have ATPase activity. They play roles in muscle contraction but do not catalyze the hydrolysis of ATP. 5. **Conclusion**: The ATPase activity in muscle is specifically associated with the myosin heads. Therefore, the ATPase of the type muscle is located in the myosin. 6. **Final Answer**: The correct answer is that the ATPase of the type muscle is located in **myosin**.
