Voici pourquoi:
* Oxidative phosphorylation is the process that produces the majority of ATP (adenosine triphosphate), the cell's energy currency. It occurs in the mitochondria and relies on a continuous supply of oxygen as the final electron acceptor in the electron transport chain.
* Anaerobic conditions mean there is a lack of oxygen. Without oxygen, the electron transport chain cannot function properly, and the production of ATP via oxidative phosphorylation is significantly reduced.
While other processes might be affected eventually, the immediate impact of anaerobic conditions is felt by the cell's primary energy-generating pathway. This lack of ATP can lead to various cellular dysfunctions and, ultimately, cell death if the anaerobic conditions persist.
