circulatory system as a
transport medium?
1. Autocrine signaling
2. Endocrine signaling
3. Direct cell-to-cell
signaling
4. Paracrine signaling
5. Synaptic signaling
Explain why a steroid Steroid hormones are hydrophobic. They would require
hormone would require a a carrier protein to carry it through the blood because it
carrier protein to transport is considered hydrophilic.
it through the bloodstream.
, Each of the following is Receptors in each family are classified by their location
true regarding cellular in the body.
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

and a hydrophobic region
in the plasma membrane.
4. Intracellular receptors
are located in the cell's
cytoplasm.
Hormones, peptides, sugars, and other hydrophobic
molecules.
List TWO specific examples
