CO2's Crucial Role: pH Buffering & Mitochondrial Function #shorts

Added: 2026-06-03

[00:00:00]CO2 does even more than that. CO2 is one of the body's primary pH buffering molecules.

[00:00:07]And this matters enormously because the electron transport chain depends on extremely precise electrochemical gradients to function properly. The mitochondria are not just moving electrons, they are pumping protons across the inner mitochondrial membrane.

[00:00:27]That proton gradient that creates the whole voltage potential that ATP synthase uses to generate ATP. So, mitochondrial respiration depends heavily on stable pH, proton balance, membrane potential, and redox stability.

[00:00:43]Low CO2 states can destabilize the entire environment. They can contribute to respiratory alkalosis, altered ion gradients, impaired oxygen unloading, vasoconstriction, oxidative stress, and mitochondrial instability.
