Question

How did mitochondria arise?

Answer 1

Mitochondria:

1. Mitochondria function as the powerhouse of the living cell and generate adenosine triphosphate (ATP).
2. The cristae of the mitochondria are the multiple folds of the inner membrane that create an increased area for chemical reactions to occur.
3. The matrix refers to the inner space of the mitochondria and is crucial for ATP production.

Origin of mitocondria:

1. It is hypothesized that mitochondria evolved from endosymbiotic alphaproteobacterium present in the archaeal host cell.
2. They are said to have originated from the symbiosis of a nucleated cell engulfed by an aerobic prokaryote.
