Question

Explain Glycolysis and its steps

Answer 1

Glycolysis is the metabolic process that serves as the foundation for both aerobic and anaerobic cellular respiration. In glycolysis, glucose is converted into pyruvate. Glucose is a six- membered ring molecule found in the blood and is usually a result of the breakdown of carbohydrates into sugars.

Answer 2

Glycolysis is the metabolic process that serves as the foundation for both aerobic and anaerobic cellular respiration. In this process glucose is converted onto pyruvate.

The steps included here are:

Hexokinase - it converts D glucose into glucose 6 phosphate. The enzyme that catalyzes this reaction is hexokinase.

Phosphoglucose isomerase - it is the arrangement of G6P into F6P by glucose phosphate isomerase.

Phosphofructokinase- with magnesium as a co factor it changes F6P into F1,6 - bisphosphate.

Aldolase- the enzyme splits F1,6- bisphosphate into two sugars DHAP and GAP that are isomers of each other .

Triphosphate isomerase - the enzyme rapidly inter converts the molecules of DHAP and GAP.

Glyceraldehyde 3 phosphate dehydrogenase - it dehydrogenates and add an in organic phosphate to glyceraldehyde 3 phosphate producing 1,3 bisphoglycerate.

Phosphoglycerate kinase- transfers a phosphate group from 1,3 biosphosphoglycerate to ADP to form ATP and 3 phosphoglycerate

Phosphoglycerate mutase- the enzyme relocates the P from 3 phosphoglycerate from the 3 rd carbon to the 2 nd carbon to form 2 phosphoglycerate.

Enolase- the enzyme removes a molecule of water from 2 phosphoglycerate to form PEP.

Pyruvate kinase - the enzyme transfers a P from PEP to ADP to form pyruvic acid and ATP.
