Detailed explanation-1: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-2: -The stage of cellular respiration that takes place in the cytosol is glycolysis. Glycolysis converts glucose into pyruvate and produces a net gain of two ATP molecules as well as the electron carrier NADH.

Detailed explanation-3: -Stages of Cellular Respiration Glycolysis occurs in the cytosol of the cell and does not require oxygen, whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen.

Detailed explanation-4: -The Location of Cellular Respiration Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.

Detailed explanation-5: -Anaerobic Respiration Definition Anaerobic (cellular) respiration is a respiratory process that occurs in both prokaryotes and eukaryotes in which cells break down the sugar molecules to produce energy without the presence of oxygen.
