The Role of Oxygen in Cellular Respiration

Ambient air is made up of 20.9% oxygen and several inert gases. However, only about a quarter of the oxygen we breathe is transferred to our blood through the alveoli in the lungs.

Understanding Aerobic and Anaerobic Respiration

In aerobic cell respiration, ambient air is inhaled and gas exchange occurs in the alveoli of the lungs. The lung acts as a diffusion organ. At the cellular level, oxygen is combined with nutrients to produce energy (ATP).

When oxygen is deficient, the body resorts to anaerobic respiration. This process produces significantly less energy and results in the incomplete breakdown of glucose, producing lactic acid. This buildup of lactic acid lowers the body's pH, making it more acidic.

The Bohr Effect

The lower the pH of the plasma (more acidic), the less oxygen will be taken up by hemoglobin, or more will be lost by it. This phenomenon is known as the Bohr effect. The main factor governing the pH of plasma is the amount of carbon dioxide in the bloodstream, which reacts with water to form carbonic acid.

How Oxygenated Water Helps

Drinking oxygen-enriched water provides an alternative delivery method for oxygen. Instead of relying solely on the lungs, oxygen is absorbed directly through the stomach and intestinal mucosa, entering the portal vein and systemic circulation. This can help bypass the limitations of pulmonary gas exchange and directly support cellular respiration, reducing reliance on anaerobic processes and mitigating lactic acid buildup.
