Question

Which eukaryotic organelles is primarily responsible for cellular digestion

Answer 1

Cellular Respiration occurs in 4 major stages: Glycolysis, NADH degeneration, Citric acid (or Kreb's) cycle and Electron Transport Chain. Glycolysis occurs in the cytosol or cytoplasm of the cell. If oxygen is present, then the next three stages would occur, otherwise lactic acid or alcohol fermentation would occur. NADH degenration and Citric acid cycle occur in the matrix of the mitochondria while Electron Transport Chain occurs in the intermembranal space of the mitochondria. Most of cell respiration occurs in the mitochondria though. Hope this helped!
I must say this is a very complete answer but if i might add,of every part of a cell involved in cellular respiration,the only organelle is the mitochondria meaning that is the answer.
