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.
Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers. The kinetochore fibers interact with the spindle polar fibers connecting the kinetochores to the polar fibers. The chromosomes begin to migrate toward the cell center. Metaphase, the spindle fully develops and the chromosomes align at the metaphase plate (a plane that is equally distant from the two spindle poles).
