Choose the correct answer from the list. Not all the answers will be used.

1. The yeast enzyme ______, produces acetaldehyde and CO₂ from pyruvate.

2. The coenzyme ______ is used as an electron sink by pyruvate decarboxylase.

3. Glycolysis always forms ____ regardless of the aerobic or anaerobic fate of pyruvate.

4. The carbon end product of aerobic glycolysis is ______.

5. The coenzyme ______ is the oxidizing agent in both aerobic and anaerobic glycolysis.

6. The only oxidation step in glycolysis is carried out by the enzyme ______.

7. A genetic deficiency of a transferase enzyme required for sugar group exchange causes the disease ______, which results in mental retardation and liver damage.

8. The enzyme _____ is the major control point for glycolysis in muscle.

9. NADPH used in lipid biosynthesis is produced by the ______ pathway.

A) phosphofructokinase B pentose phosphate CO ATP D hypoglycemia E) glyceraldehyde 3-phosphate dehydrogenase F) NADPT LG thiamine pyrophosphate pyruvate decarboxylase D galactosemia ID NADT KO phosphoglycerate kinase L pyruvate IMO glucogenic. IN PAD

Solution

1. Pyruvate decarboxylase

2. Thiamine pyrophosphate

3. ATP

4. Pyruvate

5. NAD+

6. Glyceraldehyde-3-phosphate dehydrogenase

It oxidises as well as phosphorylates glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.

7. Galactosemia

8. Phosphofructokinase

Increased levels of phosphofructokinase allosterically inhibits it and thus lowering affinity for fructose-6-phosphate. AMP reverses this action of ATP and increases affinity towards fructose-6-phosphate.

9. Pentose phosphate
