What is anaerobic respiration.

By SWA

Anaerobic respiration is a type of respiration that occurs in the absence of oxygen. It's a process used by some cells and organisms to generate energy. Unlike aerobic respiration, which uses oxygen, anaerobic respiration uses a different electron acceptor at the end of the electron transport chain.

Here are the key aspects of anaerobic respiration:

  1. Oxygen Absence: Anaerobic respiration happens when there is no oxygen available. It's common in environments that are oxygen-poor, like deep in soils, or in the gut of animals.

  2. Energy Yield: Anaerobic respiration is less efficient than aerobic respiration in terms of the amount of energy produced. While aerobic respiration can generate up to 38 ATP (adenosine triphosphate) molecules from a single glucose molecule, anaerobic respiration yields only a fraction of that.

  3. Types of Anaerobic Respiration:

    • Lactic Acid Fermentation: This occurs in muscle cells. When your muscles are overworked and run out of oxygen, they switch to anaerobic respiration, producing lactic acid as a byproduct, which can lead to muscle fatigue and soreness.
    • Alcoholic Fermentation: This is used by yeasts and some types of bacteria. It converts glucose into ethanol and carbon dioxide, and is the process used in brewing and bread-making.

  4. Electron Transport Chain: In anaerobic respiration, the electron transport chain operates differently than in aerobic respiration. Instead of oxygen, other molecules like sulfate or nitrate can act as the final electron acceptor.

  5. Byproducts: The byproducts of anaerobic respiration vary depending on the organism and conditions. Lactic acid, ethanol, carbon dioxide, and hydrogen gas are common examples.

    In some diseases, inflamed tissues might experience reduced oxygen supply, which could indirectly increase anaerobic metabolism in those tissues. But this is an indirect effect rather than a direct causation.

    Could anaerobic respiration POTS?

Anaerobic respiration is crucial in many biological processes and industries, such as wastewater treatment, fermentation in food production, and in the natural cycles of carbon and nitrogen in the environment.

Is ME CFS Spinal Muscular Atrophy (SMA)?

By SWA
After a 70-year journey filled with multiple incorrect diagnoses and just as many inappropriate treatments, I finally found an answer to my progressive muscle weakness. Throughout this time, I faced insults and was labeled lazy for my inability to walk long distances or up hills, climb steps, or carry heavy loads. I couldn't ride a bike because sitting on the saddle was impossible. My school grades suffered due to insufficient performance in sports. Instead of receiving comfort from my parents, I was pushed into hard work to strengthen my muscles. Doctors also advised me to exercise my muscles. My life continued with reduced activity, as I had to avoid or quit jobs where standing for extended periods was required or where I couldn't support my skeletal muscle weakness by bracing my elbows. The most excruciatingly painful and weakest period, when I could barely walk, occurred at age 20, during pregnancy. In 2008, an MRI referred by my endocrinologist for permanent adrenal

Cytokine Storm, Mast Cell Activation Syndrome (MCAS), Endothelial Dysfunction and microclots/thrombosis?

Could a virus be the stimulus for cytokine production?   It is well established, but rarely  tested, that a cytokine storm is an overactive immune response characterized by the excessive release of pro-inflammatory cytokines. ( ANA, CRP, and CBC tests are necessary) It can occur in various conditions, such as severe infections (e.g., COVID-19), (and other viruses), autoimmune diseases, and after certain treatments.  Serositis and lymphopenia are common features of systemic lupus erythematosus following SARS-CoV-2 infection: A case report and literature review These cells are called NKG2D+CD8+ T cells and researchers say their aggressive response is responsible for neurological damage suffered from infections beyond just Zika, like COVID-19 and even septic shock. The aggressive response is the result of the body producing large amounts of inflammatory proteins called cytokines, which in moderation help to coordinate the body’s response in battling an infection or injury by

WASF3 updated and additional information

By SWA

  WASF3 disrupts mitochondrial respiration and may mediate exercise intolerance in myalgic encephalomyelitis/chronic fatigue syndrome Significance​ Chronic fatigue is a debilitating symptom that affects many individuals, but its mechanism remains poorly understood. This study shows that endoplamic reticulum (ER) stress–induced WASF3 protein localizes to mitochondria and disrupts respiratory supercomplex assembly, leading to decreased oxygen consumption and exercise endurance. Alleviating ER stress decreases WASF3 and restores mitochondrial function, indicating that WASF3 can impair skeletal muscle bioenergetics and may be targetable for treating fatigue symptoms. Abstract​ Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by various disabling symptoms including exercise intolerance and is diagnosed in the absence of a specific cause, making its clinical management challenging. A better understanding of the molecular mechanism underlying this apparen
