What happens to an enzyme when
the temperature or pH of its
environment changes?

Extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. the changing of the pH outside of the enzyme’s range will slow the activity of the enzyme. if it’s not extreme high or low temperatures, then raising the temperature, slightly, can speed up a reaction. Lowering the temperature, slightly, slows down a reaction

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.
