3. An organ involved in gluconeogenesis is the
   1. muscle             b. kidney c. brain                        d. lung

4. An enzyme involved in gluconeogenesis but not in glycolysis is
   1. hexokinase
   2. pyruvate kinase
   3. PEP carboxykinase
   4. phosphofructokinase-1

5. The most important controlling enzyme in glycolysis is
   1. hexokinase
   2. pyruvate kinase
   3. aldolase

Answer 1

enzyme, Lys a Answer of lipoate As, Lipoic acid is an essential cofacton for the oxidative decarboxylations of a-kat acids where linked to the E-amino group of the lysine residue of the enzyme dity dro tipoyl trans e cetylase, it is one of several prostethic groups in the multi lactate dehydrogenase complex. Hence. The actual cofactor for dihydua lipayl dehydrogenas is lipoate. Answer: 2 The active site of trans aldo lose contains lys. Amswer"-3. • b In vertebrate, gluconeogenesis takes place mainly in the liver and to a lesser exter in the contex of the kidneys an organ involved in gluconeogenen is the- Ang wer 4) C. PEP carboxy kinase The enzymes unique gluconeogenesis pysuvate carboxylase, PEP carboxy kinase fructose 6 bis phosphatase So, option is right answer Anyway? 5 d) Phosphofructokinase-1 phosphofructokinase is the most important control element in the mammalian 6 kidney SO the kidney ue to Que etc. glycolytic pathing
