A hypothesis that has been rigorously tested and supported may eventually become known as a? 

In order to survive, prokaryotes such as bacteria need toproduce energy from food such as glucose. In eukaryotic cells,respiration is performed by mitochondria, but prokaryotic cells donot have membrane-enclosed organelles. How do prokaryotic cellsrespirate without mitochondria?

Discuss how organelles such as mitochondria or chloroplasts are thought to have descended from prokaryotic cells.

Production of ATP takes place in Eukaryotic cells in these organelles chloroplasts mitochondria ER Golgi bodies.
