Steroids are derived from ____
What is Cholesterol?
Protein based (peptide and glycoproteins) hormones bind to what type of receptors?
What are plasma membrane receptors?
Cells respond to signals they release themselves.
What is autocrine signaling?
The end product of the genomic steroid hormone signaling pathway?
What is the synthesis of new proteins?
The end goal of the GCPR pathway is ___.
What is protein activation? (this can be turning proteins on, enzymes on, or opening ion channels)
Cholesterol is the backbone of steroid hormones, what type of affinity do they have to lipids.
What is lipophilic?
Protein based hormones require a second messenger because ___.
What is lipophobic? (Typically they cannot enter the cell, relying on a membrane receptor to activate a second messenger)
Chemical messengers act locally on nearby cells within the same tissues.
What is paracrine signaling?
During the genomic signaling pathway to occur how does the DNA turn into protein synthesis?
What is DNA transcribed into RNA and then translated into a protein?
Once the hormone binds to its receptor, what is the g-proteins job?
What is adenylate cyclase activation?
Steroid hormones can bind to what type of receptors.
What are intercellular receptors and plasma membrane receptors?
What is a glycoprotein?
The time a hormone travels in the blood before the body will metabolize half of it.
What is a half-life?
For the non-genomic pathway, the GPCR turns on Adenylate Cyclase. Identify the job of Adenylate cyclase
What is converting ATP to cAMP?
cAMP activates protein kinases by __.
What is the removal of the inhibitory unit off the catalytic unit found on protein kinase?

What is oxytocin?
What is endocrine signaling?
Once the steroid hormone enters the cell and binds to its receptor, it creates a new structure what is the name of the structure that enters into the nucleus and binds to the DNA of the cell.
