The correct Answer is:
To solve the question regarding the importance of "tyrosine" in the formation of specific hormones, we can follow these steps: ### Step 1: Understand what Tyrosine is Tyrosine is an amino acid that plays a crucial role in the synthesis of proteins and hormones in the body. **Hint:** Recall that amino acids are the building blocks of proteins and can also serve as precursors for hormone synthesis. ### Step 2: Identify the hormones listed in the question The hormones mentioned in the question are: 1. T3 (Triiodothyronine) 2. T4 (Thyroxine) 3. Oxytocin 4. PRL (Prolactin) **Hint:** Familiarize yourself with the functions and origins of these hormones to understand their relationship with tyrosine. ### Step 3: Determine the role of Tyrosine in hormone production Tyrosine is specifically important in the synthesis of thyroid hormones, which include T3 and T4. These hormones are produced in the thyroid gland and are crucial for regulating metabolism and energy levels. **Hint:** Remember that T3 and T4 are derived from the amino acid tyrosine, while other hormones may have different precursors. ### Step 4: Analyze the other hormones - **Oxytocin** is produced in the hypothalamus and released by the posterior pituitary gland. It is involved in childbirth and lactation but does not derive from tyrosine. - **Prolactin (PRL)** is also produced in the anterior pituitary gland and is primarily involved in lactation. It is not synthesized from tyrosine. **Hint:** Think about the origin of each hormone and whether they are derived from amino acids or other compounds. ### Step 5: Conclusion Based on the information gathered: - Tyrosine is important for the formation of T3 and T4 (options I and II). - Oxytocin and PRL are not formed from tyrosine. Thus, the correct answer is **I and II**. **Final Answer:** I and II ---
