Cellular respiration - Stages With Diagrams

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb's Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

Glycolysis breaks down glucose into 2 Pyretic Acid Molecules in the Cytoplasm, releasing 2 ATP and Hydrogen

The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix. 

The Electron Transport Chain takes the electron carrying Hydrogens and releases the energy as ATP and water in the Mitochondrial Membranes.
