Question

which part of respiration is common to both aerobes and anaerobes? where does it occur inside the cell

Answer 1

Anaerobic reactions occur in the cytoplasm of the cell and aerobic reactions occur in the mitochondria of the cells. Notice in the picture below that glycolysis is happening in the cytoplasm and everything else is occurring inside the mitochondria, which require oxygen.

Answer 2

the breaking down of glucose which is a 6 carbon molecule into pyruvate in the cytoplasm of the cell is common is aerobic and anaerobic respiration
