Summary
Cellular respiration is a vital process in cells for generating energy in the form of ATP. It can take place with oxygen (aerobic) or without oxygen (anaerobic). The process initiates with glycolysis, breaking down glucose to produce pyruvate. In aerobic respiration, pyruvate enters the mitochondria to form acetyl-CoA and goes through the Krebs cycle to produce CO2, hydrogen atoms, and ATP via the electron transport chain. Additionally, in anaerobic respiration, such as lactic acid fermentation, pyruvate is converted to lactic acid in the absence of oxygen as an energy source.
Introduction to Cellular Respiration
Cellular respiration is a crucial process in cells that provides energy through ATP production. It can occur aerobically (with oxygen) or anaerobically (without oxygen). The initial step is glycolysis, where glucose is broken down to produce pyruvate.
Aerobic Respiration
In aerobic respiration, pyruvate enters the mitochondria and undergoes enzymatic processes to form acetyl-CoA. This molecule then enters the Krebs cycle in the mitochondrial matrix, leading to the production of CO2, hydrogen atoms, and ATP through the electron transport chain.
Anaerobic Respiration and Fermentation
Anaerobic respiration or fermentation occurs in the cell's cytoplasm when there is no oxygen. The pyruvate from glycolysis can enter fermentation pathways such as lactic acid fermentation, where lactic acid is produced as a source of energy.
