Solution:

Main steps in aerobic respiration are as follows

• Glycolysis: Glucose is broken down into pyruvic acid in the cytoplasm (cytosol).
• Pyruvic acid oxidative decarboxylation to acetyl coenzyme-A occurs within the mitochondrial matrix.
• TCA or Krebs cycle takes place in Mitochondrial matrix where pyruvic acid is oxidized to transform the energy contained in these molecules into ATP.
• The ATP synthase complex is involved in the electron transport chain in the mitochondrial membrane.
