Cellular respiration involves two phases. Anaerobic respiration does not involve oxygen, while aerobic respiration does.
So, anaerobic respiration includes glycolysis and fermentation takes place in cytoplasm whereas aerobic respiration take place in mitochondria. Cellular respiration is the the bunch of metabolic reaction which occur in the cell of the organism and it is helpful in converting biochemical energy into ATP after that it will release waste product.
That would be a sunspot, I believe.
Hope it helps!
