In female mice, both the glucocorticoid (cortisol) receptor and the estrogen receptor are expressed in liver cells (hepatocytes). The control element to which the glucocorticoid receptor binds is a short-strip of DNA that can accommodate the binding of the glucocorticoid receptor dimer. This control element is called a glucocorticoid response element (GRE). It is located1000 bp downstream from the poly-A site for the PEPCK gene. When this gene is activated by cortisol, it helps the hepatocyte to release glucose into...

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
described below...

Olfaction occurs when volatile compounds bind to specific
odorant receptors. In mammals, each olfactory receptor neuron in
the olfactory nasal epithelium expresses a single type of odorant
receptor. These odorant receptors constitute a large multigene
family (>1000 members) of related proteins. Binding of odorant
induces a signaling cascade that is mediated via a G protein,
Gaolf. Recent studies suggest that there are a small
number of olfactory sensory neurons in the nasal epithelium that
express members of the trace-amine associated...
