What is chemosynthesis? How do chemosynthetic organisms get energy? Some examples of organisms include colorless sulfur bacteria, iron bacteria, and giant tube worms (Riftia parchyptila).

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
