The second stage of glycolysis is an isomerization reaction. In this reaction the glucose-6-phosphate is rearranged into fructose-6-phosphate by the enzyme glucose phosphate isomerase. This is a reversible reaction under normal conditions of the cell.
Kinetochore. A specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape; the centromere is difficult to sequence. Please contribute to this project, if you have more information about this term feel free to edit this page.
â¢ Kinetochores assembles on the centromere. â¢ Centromeres are clearly visible with a light microscope as a constricted region on the condensed chromosome while kinetochrores can only be seen with the aid of an electric microscope. â¢ Unlike in the centromeres, three different layers can be found in the kinetochore.
