Glycolysis - Advance

Dear Readers,

Glycolysis is the process by which one molecule of glucose is converted into two molecules of pyruvate, two hydrogen ions and two molecules of water. Through this process, the 'high energy' molecules of ATP and NADH are synthesised. The pyruvate molecules then proceed to the link reaction, where acetyl-coA is produced.

Q1.  Harden and Young's ester is formed during glycolysis from

•  Fructose-6- phosphate
•  Glucose-6-phosphate
•  Glucose
•  None of the above

Fructose-6- phosphate

Q2.  Robinson's ester is

•  Glucose 1, 6 diphosphate
•  Glucose 6-phosphate
•  Fructose-6-phosphate
•  None of the above

Glucose-6-phosphate

Q3.  Isomerization step takes place in

•  Glycolysis
•  Krebs cycle
•   Oxidative phosphorylation
•   None of the above

Glycolysis

Q4.  Glycolysis is

•   10 step enzymatic reaction leading to formation of four carbon pyruvate
•  8 step enzymatic reaction leading to formation of four carbon pyruvate
•  10 step enzymatic reaction leading to formation of three carbon pyruvate
•  8 step enzymatic reaction leading to formation of three carbon pyruvate

8 step enzymatic reaction leading to formation of three carbon pyruvate

Q5.  Which of the following is called Newberg's ester

•  Glucose-6-phosphate
•  Fructose-6-phosphate
•  Fructose 1, 6 diphosphate

Q6.  Conversion of fructose - 6-phosphate to fructose 1,6 diphosphate is catalysed by

•  Phosphofructose kinase
•  Aldolase
•   Hexokinase
•   None of the above

Phosphofructose kinase

Q7.  Oxidation of glyceraldehyde phosphate is accompanied by

•  Oxidation of NAD⁺
•   Substrate level phosphorylation
•  Reduction of NAD⁺
•  Oxidative phosphorylation

Reduction of NAD⁺

Q8.  Excess of ATP inhibits

•  Phosphofructokinase
•  Pyruvic dehydrogenase
•  Triose phosphate isomerase
