Each of the following statements concerning peptide hormones is true EXCEPT one. Identify the EXCEPTION. Group of answer choices Peptide hormones are first synthesized as preprohormones. Peptide hormones are translated on ribosomes attached to the rough endoplasmic reticulum. Peptide hormones are translated as precursor molecules that are larger than the biologically active hormone. Peptide hormones in the bloodstream are always bound to carrier proteins. Modification of the prohormone occurs in the Golgi complex and the mature hormone is secreted from the cell by the process of exocytosis.

There are different properties of peptide hormones.  The false statement is that Peptide hormones in the bloodstream are always bound to carrier proteins.

They are usually short or long ( proteins ) chains of amino acids that are water-soluble but cannot pass through the plasma membrane by themselves alone.

Peptide hormones in the bloodstream are always bound to carrier proteins.

Explanation:

Peptide hormones are also called protein hormones owing to the fact that they are produced from amino acid chains, which are different from their counterparts made of lipids i.e. steroid hormones. Peptide hormones are first synthesized as preprohormones which undergoes series of processing to form the PROHORMONE.

The prohormone undergoes further modifications in the Golgi complex and transported via vesicles to be released as mature hormones via exocytosis. Like every proteinous molecule, peptide hormones translated on ribosomes attached to the endoplasmic reticulum i.e. RER.

However, peptide hormones are hydrophilic in nature and hence will dissolve and move easily in aqueous environment without the need of carrier proteins. Carrier proteins are needed for water-fearing (hydrophobic) molecules.
