BIOD 101 Module 5 (EXAM) questions with
|\ |\ |\ |\ |\ |\ |\
answers
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 - CORRECT ANSWERS ✔✔Endocrine
|\ |\ |\ |\ |\ |\ |\
signaling.
Explain why a steroid hormone would require a carrier protein to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
transport it through the bloodstream. - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔Steroid hormones are hydrophobic. They would require a
|\ |\ |\ |\ |\ |\ |\ |\
carrier protein to carry it through the blood because it is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
considered hydrophilic. |\
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. -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Receptors in each family are classified by
|\ |\ |\ |\ |\ |\ |\ |\
their location in the body.
|\ |\ |\ |\ |\
List TWO specific examples of cellular ligands. - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Hormones, peptides, sugars, and other hydrophobic
|\ |\ |\ |\ |\ |\
molecules.
|\
So calcium and female sex hormones would classify as ligands.
