The products of cellular respiration are carbon dioxide and water and the chemical energy is released in the form of ATP.
The initial stage of cellular respiration takes place in the cytoplasm.
Several enzymes that are involved in the process of cellular respiration are synthesized on the surface of the endoplasmic reticulum.
Mitochondria (tiny, numerous organelles), referred as powerhouses of the cell, for it is within them that energy is released from organic molecules by the process of cellular respiration. This organelle is concerned with the oxidation of food substances to release CO2, water and energy in the form of Adenosine Tri Phosphate (ATP).
