why glycolysis occurs in cytoplasm not in mitochondria?

Question

Is there any significance of this? why it can be in mitochondria .

Answer 1

 The most general answer is because this is where the enzymes are located that are involved in glycolysis. If the enzymes that were needed for glycolysis were not present in the cytosol ... then it would not be able to take place there. The mitochondria simply does not contain the enzymes inside it to perform glycolysis nor does it sufficiently have the membrane transport proteins to take glucose inside. This is the simple answer.
