Final answer:

The hormone that is NOT a tyrosine derivative is Cortisol (A). Tyrosine derivatives include thyroid hormones, epinephrine, and norepinephrine, while cortisol is a glucocorticoid derived from cholesterol.

Step-by-step explanation:

The correct answer to the question - Which of the following is NOT a type of Tyrosine Derivative? is (A) Cortisol.

Tyrosine derivatives are hormones synthesized from the amino acid tyrosine. Tyrosine derivatives include thyroid hormones, and the catecholamines, such as epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. The adrenal medulla secretes epinephrine and norepinephrine as part of the fight-or-flight response.

Cortisol, however, is a glucocorticoid hormone produced by the adrenal cortex, not a tyrosine derivative. It is involved in the regulation of metabolism, the immune response, and stress responses, among other functions, but it is synthesized from cholesterol instead of tyrosine.
