1. Why cooking ae well as gastric acid are important in
protein digestion? Explain in short in your own words.
2. The Krebs cycle serves as pathway for metabolic
interconversion. Explain in short with examples.
3. How endothermic reactions can be linked to the overall
hydrolysis of ATP → ADP and phosphate? Explain in detail.
4. Describe the formation of ketone bodies and explain their
importance in fasting and starvation
a) Explain why “blinding” should be used in an
experiment?
b) Name the four main principles of a statistical experiment?
Explain each principle and why they are important.
B. What is the most plausible trade model (theory) that should
be used to explain why Paris and Rome are still the MOST IMPORTANT
fashion centers (Chanel, Vuitton, Pierre Cardin, Zegna, Ferragamo
etc.,) or Switzerland is the center of high quality watch
manufacturing (Patek Philippe, Breguet, Rolex etc., ) despite the
fact that labor costs are relatively high in these countries and
cities. Explain and DRAW A GRAPH TO ANALYZE THE SITUATION.
1.
Why do ketones not yield to a silver mirror?
2. Why is HNO3 (nitric acid)
suitable for removing the silver mirror? Write a chemical
equation to support your answer.
A) Explain the digestion that occurs in the oral cavity.
B) What is the function of the liver in digestion?
C) What role does the gallbladder play in digestion?
D)Why is the orientation of muscle in the stomach wall
important? How does this contribute to its function?
Consider the titration of a weak base (B- ) with a strong acid
(HCl). Draw (this can be hand drawn) a pH (not pOH) vs mL HCl graph
(it will not look the same as the one in question #13; if you start
with a weak base, will the pH be low or high? As H+ is added, will
the pH increase or decrease?). Label the titration curve with
letters A-E, and describe the relative quantities of the
dissociated base...
