Cellular Respiration By rose gabriel

Formula: C6H12O6 + 6O2 ------> 6CO2 + 6H2O Glucose + Oxygen -----> Carbon Dioxide + Water. Catabolic reaction

Steps of Glycolysis: Is the first step in both cellular respiration and fermentation. It occurs in both aerobic and anaerobic. It takes place in the cytoplasm. Occurs in prokaryote and eukaryote. The formula is Glucose ---> Pyruvic Acid. Or C6H12O6 ---> 2C3H4O3. A net of 2 ATP are made in gylcolysis. Also 2 NADH are made similar to NADPH but only for the mitochondria.

Steps of Krebs Cycle: Is the second step in cellular respiration. Takes place in the matrix of mitochodria. The pyruvic acid is broken down into carbon dioxide. More NADH are made in the krebs cycle. Also FADH2 are made which is also similar to ATP and NADH. The krebs cycle also releases 2 more ATP.

Steps of the Electron Transport Chain: The electron transport chain is also known as the oxidative phosphorylation. It occurs in the cristae of the mitochondria. NAHD and FADH2 are used in the process. The high energy electrons that come from the Krebs Cycle are used to convert ADP into ATP. Oxygen is a reactant and water is a product. Electron Transport Chain makes 34 ATP.

Overall Importance: It helps with energy for everything. We have energy in our food and in plants almost about everything. If we didnt have energy in our plants then our plants would be dead and then we would die because plants would not be alive to help us with oxygen. If we did not have food also we wouldnt have anything to eat which would also kill us. Energy is literally in everything and we need energy in everything to be able to survive.
