What is the net products of catabolism of one glucose in Glycolysis pathway ?

What is Glycogenesis and what is the name of the enzyme that catalyzes it ?

What is the effects of Insulin and Glucagon on Glycogenesis ?

Expert Solution

The reaction generating NADH in the Glycolysis pathway is reaction no. 6. It will generate two molecules of NADH as Dihydroxyacetone phosphate will also be converted to Glyceraldehyde 3 Phosphate which will convert to 1,3 Bisphosphoglycerate with help of enzyme dehydrogenase and NADH is produced.

The allosteric enzyme in the Glycolysis pathway is Phosphofructokinase which catalyzes the reaction no. 3. This enzyme helps in the regulation of glycolysis. It is inhibite by ATP, Citrate and acidic pH whereas stimulated by AMP, ADP, Fructose 2,6 bisphosphate.. Glycolysis:

Glucose+2 NAD + 2 ADP+ 2 pi------> 2 Pyruvate+ 2 NADH+ 2 H + 2 ATP + 2 H2O.

Glycogenesis is the polymerization of glucose into glycogen. thermodynamically it is an endergonic process and requires ATP and UTP. It occurs mainly in the muscle and the liver.

Glycogen synthase is the key enzyme of the glycogenesis that links two glucose residues on an already existing chain of glucose molecules.

glucagon increases glycogen breakdown whereas insulin enhances glycogenesis.

Write out the pathway of glycolysis. You must name each molecule in the process, the enzyme at each step, and identify coenzymes used and with which enzymes they are used. Identify a point of regulation in this pathway. If there is insufficient oxygen available to convert pyruvate to acetyl CoA, show the pathway that describes the fate of pyruvate (you must show pyruvate, and the enzyme and co-enzyme involved in the conversion of pyruvate to its metabolite)(20 points).

The enzyme enolase catalyzes the following reaction in the glycolysis pathway (Chapter 14): 2-phosphoglycerate ® phosphoenolpyruvate + H2O Dehydration of 2-phosphoglycerate (2PG) results in phosphoenolpyruvate (PEP), which is a high-energy phosphate donor that can be used to phosphorylate ADP to make ATP. Thus, this is an important reaction to set up the final step of the pathway. Balantidiasis is a disease caused by the ciliated protozoan, Balantidium coli. As it is a eukaryote, antibiotics against bacteria will not affect it....

1. What is the major byproduct of anaerobic glycolysis: ATP, NADH, lactate, or pyruvate? 2. Glucose is retained in cells because it is phosphorylated, degraded, bound, or modified by amylase? 3. Is the final product of glycolysis acetyl CoA, glucose, lactate, or pyruvate? 4. Does Glycolysis generate no ATP, 1 ATP, 2 ATPs, or NADH? 5. Are DNA ends replicated by DNA polymerase, telomerase, RNA polymerase, or primase?

Glycolysis and fatty acid oxidation are both affected by the [NADH]/[NAD+] ratio in the cell. If the conditions inside a cell are such that [NADH] >>[NAD+] what will be the effect on both pathways? Be sure to explain the direct connection between [NADH] and specific reactions in these and related pathways.
