Plutchik suggested we have 8 primary emotions that combine to form secondary emotions. Putchik identified ten postulates on which his evolutionary theory of emotions is based. Plutchik's wheel of emotion illustrates the relationships between his primary emotions and other related emotions.

The reactions of glycolysis are made up of ten steps, out of the ten step three are irreversible, this is because, these reactions have large negative free energies The three steps that are irreversible are:
1. Phosphorylation of glucose.
2. Phosphorylation of glucose 6 phosphate and
3. Transfer of phosphate from phosphoenolpyruvate to ADP.
The spindle fibers produced by the centrioles are necessary for the division of the chromosome at the time of the anaphase. In case, the centrioles do not perform their task, the genetic material in the cells may not divide equally due to the lack in the separation of the chromosomes. Hence, the problem with the centrioles may lead to the unequal division of the genetic material during the cell division process.
Hence, the correct answer is centrioles.
