Stem cells can be pluripotent, totipotent or multipotent depending on where they are sourced. This means that they are capable of differentiating into a wide variety of cells. Stem cells can, therefore, be harvested and induced to differentiate into cells or tissues that are intended to be repaired.
They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate. This increases the reaction rate.
