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 are formed in this stage when proteins connect to the centromeres. Microtubules connect to these which help the chromosomes begin moving. During metaphase, spindle fibers work to align the chromosomes into the middle of the nucleus of the cell by creating a metaphase plate.
