,Version Exam 5.1
Question 1
Which Of The Following Signaling Types Is Used To Transmit Ligands To Their Target
Cells Over Long Distances, Using The Circulatory System As A Transport Medium?
1. Autocrine Signaling
2. Endocrine Signaling
3. Direct Cell-To-Cell Signaling
4. Paracrine Signaling
5. Synaptic Signaling
Question 2
Explain Why A Steroid Hormone Would Require A Carrier Protein To Transport It
Through The Bloodstream.
Steroid Hormones Are Hydrophobic. They Would Require A Carrier Protein To Carry It
Through The Blood Because It Is Considered Hydrophilic.
,Question 3
Each Of The Following Is True Regarding Cellular Receptors Except:
1. Receptors In Each Family Are Classified By Their Location In The Body.
2. Most Receptors Are Located On The Outside Of A Cell, Anchored In The Plasma
Membrane.
3. Cell Surface Receptors Contain An Extracellular Region, Intracellular Region,
And A Hydrophobic Region In The Plasma Membrane.
4. Intracellular Receptors Are Located In The Cell's Cytoplasm.
ANS. 1
List TWO Specific Examples Of Cellular Ligands.
1. Hormones, Peptides, Sugars, And Other Hydrophobic Molecules.
2. So Calcium And Female Sex Hormones Would Classify As Ligands.
