Question

How does oxygen deprivation affect cellular respiration?

Answer 1

Effect of low oxygen concentration:

1. When our blood doesn't carry enough oxygen to our tissues to meet our body's needs, hypoxia (low oxygen in our tissues) might result from hypoxemia (low oxygen in your blood).
2. Hypoxia is a medical condition in which there is insufficient oxygen reaching the tissue level in a particular area of the body.
3. It is a disorder that impairs regular body activities by causing insufficient oxygen levels in the tissue.
4. Hypoxia can be local, affecting only a specific area or part of the body, or generalized, affecting the entire body.
5. It differs from hypoxemia, which is defined by oxygen deprivation in the blood.
6. Tissues that are hypoxic lack a sufficient supply of oxygen. If hypoxia progresses to anoxia, which is a severe case of hypoxia and signifies a complete lack of oxygen in the tissues, it may prove fatal.
7. Blood flow decreases below a critical level during hypoxic damage. This reduction is essential to keep cells alive.
8. Anaerobic metabolism and loss of adenosine triphosphate (ATP) occur when oxygenated blood is not delivered to cells, resulting in cellular membrane breakdown and anaerobic metabolism.
9. Hypovolaemia/hypotension, pressure sores, heart failure, myocardial infarction, shock, and pulmonary embolism are all examples of injuries that can produce cellular alterations.
10. If left untreated, any of these conditions can obstruct tissue perfusion, oxygen transport, and ATP production, resulting in a loss in energy, nutritional availability, and ultimately hypoxia, which can cause substantial cell damage.
