There are two types of Hormone Action. They are classified as either ______________________or
_________________________.
Steroid Hormone Action
Once secreted by the endocrine gland, a steroid hormone crosses a target cell ____________________.
Once it enters the cell, it combines with a _____________________ __________________. This
receptor is either in the ___________________ or ______________________of the cell. The hormone
and the protein receptor combined is called the ________________ ________________ ____________.
This activates ____________________of mRNA molecules from DNA. The mRNA strand of molecules
leave the nucleus and enters the _____________________________ and begins the process of
______________________ ___________________. These newly synthesized proteins produce a
hormone’s _____________________effects.
Nonsteroid Action
Once secreted by the endocrine gland, a nonsteroid hormone is carried by _______________
____________ to the _______________________ _________________. The hormone binds to the
______________________ on the cell membrane of its target cell. The ____________protein is
activated, which then activates molecules of the enzyme _______________ ____________________.
This converts ATP into ______________________ _____________________ ____________________,
also known as cAMP. cAMP activates __________________ ____________________. Protein kinases
are enzymes that modify other proteins by chemically adding phosphate groups to them. Phosphates
provide _________________. The ________________________processes of the cell changes as a
result, which produce the hormone’s ______________________.
