What role does pyruvic acid play in cellular respiration?

Pyruvic acid or pyruvate is a product of broken-down glucose during glycolysis. It is an ingredient in cellular respiration processes including the Kreb's cycle where it is transformed into lactate. It is also used to supply and distribute oxygen to cells through the citric acid cycle.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
