Krebs and colleagues identified the intermediates in a series of experiments where they took short chain acids known to be in the cell and added them to enzyme extracts from eukaryotic sources. How would they know if a given acid was an intermediate?

The correct answer would be they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur all year long.

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.
