exert phgy force at a distant target
what are the two main categories of hormones - Answer-
hydrophilic
lipophilic
what are hydrophilic hormones like - Answer-highly water
sol
low lipid sl
unbound to carrier molec in the plasma
what are types of hydrophilic hormones - Answer-peptides
pro
amines
,2|Page
what are peptides like - Answer-hydrophilic hors
short chains of AAs
dissolved in plasma
how are peptides syn - Answer-pre hor are syn in ER ribos
pre hor travel thru ER and golgi and processed into act hor
and packed into secretory vesicles
these packed hor can be stored until cell recieves
