Glycolysis Explained in 10 Easy Steps (With Diagrams)

6/27/2019The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P) This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI) As the name of the enzyme suggests this reaction involves an isomerization reaction

Multienzyme System

One of the simplest industrial examples of cell-free biotechnology is the use of glucose isomerase to produce fructose from glucose for food applications In this case glucose isomerase is very stable and doesn't require purification before use so unpurified enzyme is immobilized on a solid support as a low-cost and re-useable catalyst

Metabolic Pathways to Break Glucose into Pyruvate

The following points highlight the three main metabolic pathways to break glucose into pyruvate The phosphate is rapidly and reversibly converted to glyceraldehyde 3-phosphate by the enzyme triose phosphate isomerase This reaction completes the In this reaction the enzyme phosphoglycerate mutase catalyses a reversible

Glycolysis

• The enzyme is aldolase • Reaction 5: DHAP and GAP are isomers of each other and can readily inter-convert by the action of the enzyme triose-phosphate isomerase • GAP is a substrate for the next step in glycolysis so all of the DHAP is eventually depleted So 2 molecules of GAP are formed from each molecule of glucose Step-wise

LAB Enzymatic Activity of Lactase

You will monitor the enzyme activity using test strips that measure the level of glucose in the reaction mixture Because glucose is a product of lactose hydrolysis measuring the amount of glucose gives a direct measurement of the extent of the reaction These are the same strips that diabetics use to monitor glucose levels with a home test kit

Enzymes

The enzyme speeds that reaction up tremendously For example the sugar maltose is made from two glucose molecules bonded together The enzyme maltase is shaped in such a way that it can break the bond and free the two glucose pieces The only thing maltase can do is break maltose molecules but it can do that very rapidly and efficiently

The Activity of the Lactase Enzyme

The lactase enzyme only achieves its optimal performance if magnesium is present and it functions best when the pH is close to 6 When the enzyme is fully saturated -- in other words when the concentration of lactose is so high that increasing it further doesn't increase the reaction rate -- it can break down 60 molecules of lactose a second
