Step 1: Understanding the Concept:
Myoglobin is an oxygen-binding protein.
It is found in muscle tissue.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the function of myoglobin.
Step 3: Detailed Explanation:
Myoglobin binds oxygen in muscle tissue.
Binding of oxygen to myoglobin facilitates its diffusion.
It acts as an oxygen store and transport molecule.
It does not directly participate in absorption or metabolism.
Thus, it facilitates oxygen diffusion.
Step 4: Final Answer:
Binding of oxygen to myoglobin facilitates its diffusion.
Hence, the correct option is (B).
