Full origin of mitochondria →Frequently Asked Questions
What do mitochondria do?
They carry out cellular respiration, turning sugars and oxygen into ATP, the molecule cells use to power almost everything they do. They also help regulate calcium levels and controlled cell death.
Is it mitochondria or mitochondrion?
Mitochondrion is the singular and mitochondria the plural, following the Greek pattern. So "a mitochondrion has two membranes" but "the mitochondria are damaged".
Why are mitochondria called the powerhouse of the cell?
Because they generate most of the cell's chemical energy. The phrase comes from school biology teaching and is a simplification, since mitochondria also regulate signalling, metabolism and cell death.
