Cellular respiration By: Isabella rodrigues

Cellular respiration formula- C6H12O6 + 6O2 ----> 6CO2 + 6H20 + 38 ATP

Cellular respiration is a catabolic reaction.

Glycolysis- Occurs both with and without oxygen. Glycolysis takes place in the cytoplasm. It occurs in both prokaryote and eukaryote organisms. Glucose is the reactant and pyruvic acid is the product. 2 ATP and 2 NADH are made.


Krebs cycle- Takes place in the matrix of the mitochondria. Krebs cycle is a aerobic process. Pyruvic acid is broken down into carbon dioxide. NADH, FADH2, and 2 ATP are made.

Krebs cycle

Electron transport chain- Takes place in the cristae of the mitochondria. All aerobic organisms got through the process of the electron transport chain. Oxygen is the reactant and water is the product. 34 ATP is produced.

Electron transport chain

Cellular respiration is important because because it provides the energy for living organisms to perform all of the other necessary functions to maintain life. Most single-celled organisms, such as bacteria, do not require much energy and are able to survive on glycolysis and fermentation
