What are the main steps in aerobic respiration ? Where does it take place ?

Explanation

The main steps in aerobic respiration are as follows :
1. Glycolysis : It is the break down of glucose to pyruvic acid and occurs inside the cytosol of cytoplasm.
2. Oxidative decarboxylation of pyruvic acid to acetyl coenzyme-A. It occurs inside the mitochondrial matrix.
3. Tricarboxylic acid cycle or Krebs cycle that occurs inside the mitochondrial matrix.
4. Electron transport system and oxidative phosphorylation that occurs in the inner mitochondrial membrane involving ATP synthase complex.
