3. Figures to the right indicate full marks.
Marks
Q.1 (a) Write down the reaction for formation of acetyl Co A from pyruvate 03
(b) Draw structure of Ribose, Glucose, Arabinose and Fructose 04
(c) Draw TCA cycle showing appropriate components and give its
importance.
07
Q.2 (a) Write the net biochemical equation for the metabolism of a molecule of
glucose by glycolysis and the citric acid cycle, including all cofactors.
03
(b) Draw glyoxylate cycle with related . 04
(c) Explain Gluconeogenesis pathway with its significance 07
OR
(c) What are various metabolic disorders and what can be done about it ?
discuss
07
Q.3 (a) Why peptide bond has planer configuration? 03
(b) Write a short note on fate of pyruvate after glycolysis 04
(c) What do you mean by domain and motif? Explain super secondary
structural elements with drawings.
07
OR
Q.3 (a) Enlist and explain functions of carbohydrate in biological system. 03
(b) Soy sauce is pre- pared by fermenting a salted mixture of soybeans and
wheat with several microorganisms, including yeast, over a period of 8
to 12 months. The resulting sauce (after solids are removed) is rich in
lactate and ethanol. How are these two compounds produced? To prevent
the soy sauce from having a strong vin- egary taste (vinegar is dilute
acetic acid), oxygen must be kept out of the fermentation tank. Why?
