Lithium ion, which is used to treat bipolar disorder, interferes with the phosphoinositide signaling pathway by inhibiting enzymes such as inositol monophosphatase and inositol polyphosphate 1-phosphatase. Predict the eff ect of Li+ on the supply of cellular inositol, a precursor of phosphatidylinositol and PIP2.
The epinephrine-mediated “amplificationcascade” of Figure 24.14 has six steps, all of which are catalyticwith one exception. This cascade leads to the activation of glycogenphosphorylase. This enzyme acts in turn on glycogen to yieldglucose-1-phosphate (G-1-P).(a) Which step is not catalytic?(b) If each catalytic step had a turnover (molecules of substrateacted on per molecule of enzyme) of 10, how many moleculesof G-1-P would result from one molecule of epinephrine?(c) What is the biochemical advantage of such a cascade?(d) How is the amplification cascade of this questionreversed?
Hormone H regulates these effects via its receptors which are found at both the cell surface (csRH) and within the cell (içRH). The signalling pathways that become activated in the presence of hormone H are depicted and described below. hormone H.

Tumor necrosis factor (TNF) signaling Discuss the nature of the TNF ligand and the receptor for that ligand, and explain the general steps in the pathway (use figure 8.53 and explain in your own words). Make sure to include an explanation of the proteolytic and phosphorylation cascades. What advantage is there in having a cascade part of these pathways? What purpose does it serve?
Histamine binds to the H1 G-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated G-protein’s alpha subunit prevented the hydrolysis of GTP how would the allergic response change? More severe allergic response compared to normal G-protein signaling. Less severe allergic response compared to normal G-protein signaling. No allergic response. No change compared to normal G-protein signaling.

At body temperature, L-aspartate in proteins race-mizes to D-aspartate at an appreciable rate. Most pro-teins in the body have a very low level of D-aspartate, if itcan be detected at all. Elastin, however, has a fairly highlevel of D-aspartate. Moreover, the amount of D-aspartateincreases in direct proportion to the age of the person fromwhom the sample was taken. Why do you suppose thatmost proteins have little if any D-aspartate, while elastinhas levels of D-aspartate that increase steadily with age?
Receptor, especially growth factor receptor signaling is deregulated in cancer cells, which results in uncontrolled growth. The alterations responsible for this may be due to a truncated receptor, or change from normal paracrine to autocrine signaling or ligand (growth factor) independent firing or overexpression of a receptor Explain how each of these changes results in excessive signaling by the receptor.
EGTA is a chelating agent with high affinity and specificity to Ca2+.
