The correct Answer is:
To solve the question regarding the percentage of `alpha_(2)beta_(2)` globin present in human adults, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Hemoglobin Structure**: - Hemoglobin is a quaternary protein composed of four polypeptide chains: two alpha (α) chains and two beta (β) chains. This structure is represented as `α_(2)β_(2)`. 2. **Identify the Composition of Adult Hemoglobin**: - In adults, the predominant form of hemoglobin is Hemoglobin A (HbA), which consists of the `α_(2)β_(2)` configuration. 3. **Determine the Percentage of `α_(2)β_(2)` Globin**: - It is known that approximately 97% of the hemoglobin in adult humans is in the form of `α_(2)β_(2)`. 4. **Conclusion**: - Therefore, the percentage of `α_(2)β_(2)` globin present in human adults is approximately 97%. ### Final Answer: - The percentage of `α_(2)β_(2)` globin present in human adults is **97%**. ---
