Question
What type of hormone is transported in the blood bound to a plasma protein?
- protein hormones
- amine hormones
- steroid hormones
Solution
Answer
The type of hormone that is typically transported in the blood bound to a plasma protein is steroid hormones.
Explanation
-
Protein Hormones: These hormones are usually water-soluble and circulate in the bloodstream unbound, meaning they do not need plasma proteins for transport.
-
Amine Hormones: Although some amine hormones can be bound to proteins, many of them are also water-soluble and circulate freely in the blood.
-
Steroid Hormones: These hormones are lipid-soluble, which means they cannot dissolve well in the watery environment of the blood. As a result, they are primarily transported bound to plasma proteins, which helps to increase their solubility and prolong their half-life in circulation.
Thus, the correct choice is steroid hormones.
