The process of glycolysis begins when ___ bind to glucose. NAD+ is reduced in the process. Finally, ___ is produced/released to ultimately be used by the [Krebs cycle]

Step 1

The word glycolysis made up of two words glucose and lysis mean break down. The glycolysis is a metabolic pathway that involved the systematic breakdown of glucose and glycolysis process occur in the cytosol of the cell.

Step 2

In glycolysis one molecule of glucose which is 6 carbon compound which is broken down into 2 molecule of pyruvate which is 3 carbon compound and, in this conversion, energy is released in the form of ATP and NADH. The pyruvate form is further utilizing various energy-producing pathways that produce more energy. The process of glycolysis takes place into two phases in the first phase the glucose is converted into glyceraldehyde-3-phosphate. since this conversion involved the addition of phosphate in first step energy is used instead of release.


In the second phase glyceraldehyde-3-phosphate converted into pyruvate and as it is second phase energy is produced.


Here glucose ring is phosphorylated addition of phosphate group to a molecule derived ATP. This reaction occurs with the help of enzyme hexokinase that catalyzes the phosphorylation of a much six-membered glucose ring structure. 

Step 3

In this process final step with the help of pyruvate kinase enzyme transfers a P form phosphoenolpyruvate (PEP) to ADP to form pyruvic acid and ATP. This reaction involves the transfer of phosphate groups. The phosphate group attached to the 2’ carbon of PEP is transferred ...
