BIOD 101 MODULE 5 EXAM
Which of the following signaling types is used to transmit ligands to their
target cells oṿer 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
Endocrine signaling.
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.
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.
Receptors in each family are classified by their location in the body.
List TWO specific examples of cellular ligands.
Hormones, peptides, sugars, and other hydrophobic molecules.
So calcium and female sex hormones would classify as ligands.
Fill in the Blank:
Transduction is the chain of ___________ and intracellular ___________
that relay signals inside of a cell.
1. Molecules
2. Enzymes
Which of the following statements is true of GPCRs?
