You just discovered, for the first time, that LTP causes learning. Describe the molecular changes involved in LTP. The answer should include: how AMPA and NMDA receptors are different, why this matters, how a particular protein kinase is activated, two important ways this protein kinase contributes to LTP, how a particular transcription factor is activated, how the transcription factor contributes to LTP, how retrograde messengers contribute.

How are chemical changes summarized in a form of balanced chemical equations? What important reaction information is needed to write a complete balanced chemical equation?
Why is it necessary to write a balanced equation to completely understand the chemical properties of the reactants and products, and predict if a reaction has occurred or not?

1. Two reactions involving L-amino acids and the values of their respective free-energy changes are as follows:
Glutamate + pyruvate « a-ketoglutarate + alanine
DG°‘ = -2.4 kcal/mol
Glutamate + oxaloacetate « a-ketoglutarate + aspartate
DG°‘ = -11.5 kcal/mol
a) Write the overall reaction for production of alanine and oxaloacetate from aspartate and pyruvate.
b) Show that under standard conditions the net formation of alanine and oxaloacetate from aspartate and pyruvate is thermodynamically unfavorable.
c) Suppose that at 25 °C, the molar concentrations of reactants and products are as follows:
[pyruvate] = [aspartate] = 10 -2 M
[alanine] = 10-4 M
[oxaloacetate] = 10-5 M
Is the spontaneous synthesis of alanine and oxaloacetate possible under these conditions?

Q1. Price elasticity of demand measures
A) how responsive suppliers are to price changes.
B) how responsive sales are to changes in the price of a related good.
C) how responsive quantity demanded is to a change in price.
D) how responsive sales are to a change in buyers' incomes.
Q2. Suppose the value of the price elasticity of demand is -3. What does this mean?
A) A 1 percent increase in the price of the good causes quantity demanded to increase by 3 percent.
B) A 1 percent increase in the price of the good causes quantity demanded to decrease by 3 percent.
C) A 3 percent increase in the price of the good causes quantity demanded to decrease by 1 percent.
D) A $1 increase in price causes quantity demanded to fall by 3 units.
Q3. If the percentage increase in price is 15 percent and the value of the price elasticity of demand is - 3, then quantity demanded
A) will increase by 45 percent. B) will increase by 5 percent.
C) will decrease by 45 percent. D) will decrease by 5 percent.

A) 0.17 B) 0.62 C) 1.62 D) 5
Q.5 Rank these three items in terms of the elasticity of the demand for them at any given price, from most elastic to least elastic: hot beverages, coffee and Peets' Coffee.
A) hot beverages, coffee, Peets' Coffee
B) Peets' Coffee, coffee, hot beverages
C) coffee, Peets' Coffee, hot beverages
D) coffee, hot beverages, Peets' Coffee
Q.6. Income elasticity measures
A) how a good's quantity demanded responds to change in the goods price.
B) how a good's quantity demanded responds to change in the price of another good.
C) how a good's quantity demanded responds to change in buyers' incomes.
D) how a good's quantity demanded responds to producers' incomes.
Q.7 Last year, Sefton purchased 60 pounds of potatoes to feed his family of five when his household income was $30,000. This year, his household income fell to $20,000 and Sefton purchased 80 pounds of potatoes. All else constant, Sefton's income elasticity of demand for potatoes is
A) negative, so Sefton considers potatoes to be an inferior good.
B) positive, so Sefton considers potatoes to be an inferior good.
C) positive, so Sefton considers potatoes to be a normal good and a necessity.
D) negative, so Sefton considers potatoes to be a normal good.

How sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures, in degrees Celsius, and mean coral growth, in centimeters per year, over a several‑year period at locations in the Gulf of Mexico and the Caribbean Sea. The table shows the data for the Gulf of Mexico.
