Idenity the process that occurs within the sun that converts mass into large amount of energy

The process is nuclear fusion. Here, usually, the nuclei of hydrogen atoms or helium atoms. The process releases huge amounts of energy, enough to oppose the force of gravity present at the centre of the star

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.
