Answer:
Messenger RNA on the ribosomes binds amino acids into a peptide chain called a preprohormone. the chain is directed into the ER lumen by a signal sequence of amino acids
-enzymes in the ER chop off the signal sequence, creating an inactive prohormone
-the prohormone passes from the ER through Golgi
-secretory vesicles containing enzymes and prohormone bud off the golgi. the enzymes chop the prohormone into one or more active peptides
-vesicle releases contents by exocytosis
-hormone moves into circulation for transport to its target
<h2>The answer is RNA</h2>
The answer is d. Just so you know
The answer for the above question is Cardiovascular fitness. It is the ability of the heart, lungs, and blood vessels to function efficiently when a person exercises. Cardiovascular system is the body system that includes the heart, blood vessels, and blood, and functions by transporting oxygen and nutrients to body cells and removing cellular wastes.
