Cristae:

These are folds in the inner membrane of mitochondria where much of cellular respiration occurs. They're like solar panels collecting sunlight to generate electricity.

Matrix:

The fluid inside mitochondria where some stages of cellular respiration occur. It's akin to the control room in our power plant analogy, where all operations are monitored and managed.

Mitochondrial DNA:

This is DNA located in mitochondria; it is inherited only from one’s mother. Consider this as unique blueprints used only by the power plant.
