I does not “access” the oxygen.

The receptors it connects to in the hemoglobin cause the release of the red blood cells iron. Iron is what binds the oxygen. Iron release winds up releasing the oxygen. It is an indirect action that causes the release of the oxygen, not a direct attack on, or access to the oxygen. The effect is the same - hemoglobin cannot deliver as much oxygen.

When patients are identified and brought in early, low oxygen levels are noticed, but the lungs, the bronchial tubes, the heart and the whole respiratory system looks fine, yet the patient is breathing harder than they should be - missing oxygen even though the respiratory system is working normally.

But, slowly, with the lack of oxygen in the hemoglobin (not delivering oxygen to cells) and the free roaming oxygen in the blood, damage grows on internal tissues, including the respiratory system. Unfortunately too many serious cases do not get to the doctor or the hospital before the ancillary damages to the respiratory system have begun, and what the doctor sees is a damaged respiratory system and thinks the central cause was a direct attack on the respiratory system. It was not that, initially, it begins with the chemistry of detaching the iron in the hemoglobin which - the iron - had bound the oxygen. The brain knows only that oxygen is not finding its way around the body and the main signal it has is to tell the respiratory system to get more.

Here are some links, among many others.

Why does Hydroxychlorquine work? IT binds heme (the parts of hemoglobin) blocking Covid-19’s entry there, blocking the Covid-19 action that releases the iron there, which released the oxygen.

Thank you for trying to help me!
I don’t know what you meant about accessing the oxygen.
if You can explain what those “hemoglobin receptors” would be that would help.
Also what is the chemistry for HcQ binding heme?

I can’t read those links yet but thanks I’ll get it. If the answers are there just point me with my thanks!
Would you read the article I linked and tell me where it goes wrong?

I appreciate the chance to learn.
