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.
Centromere is the 'waist' of a chromosome. The structure where mitotic spindles attach to the kinetochore while centrosome is an organelle where microtubules are formed in some cells. Centrosome contains a paired centriole.
