Q&A

• What does the speaker emphasize about acid excretion in general? 💧

  The speaker emphasizes that the body excretes several types of acids, including uric acid and weak acids through urine. They aim to correct any misleading claims regarding the body's acid excretion processes and underscore the roles that different molecules play in these processes.

• What is the speaker's stance on the presence of ammonia and pH levels? 🔬

  The speaker refutes claims that ammonia does not exist at certain pH levels, stating that it is present even at low percentages, specifically 1.7% at pH 7.4. They argue that there is no definitive cutoff for ammonia's existence based on pH.

• How does the alkaline tide relate to acid production? 🌊

  The alkaline tide refers to the phenomenon where bicarbonate is produced by parietal cells during acid production, which affects stomach acidity. The speaker explains that bicarbonate can make blood more alkaline while also asserting their prior knowledge of hydronium ion production and its implications.

• What is the truth about ammonia production in the body? 📊

  The speaker corrects misleading claims about calcium supplements and states that ammonia is indeed produced by the body and excreted with uric acid. They clarify that ammonia is present in physiological concentrations and that its presence is not negated by pH levels.

• What misconceptions about acid excretion does the speaker address? 🧪

  The speaker explains that uric acid, ammonium, and dihydrogen phosphate are excreted in urine. They emphasize that uric acid exists largely undissociated at low urinary pH levels, specifically, that about 70% remains undissociated when the pH drops to 5.

• How does the speaker clarify the role of hydronium ions? 🔍

  The speaker clarifies that acids exist as hydronium ions, emphasizing that this topic has been addressed in their earlier content. They challenge misconceptions about acid-base balance and refute accusations regarding misinformation on supplement promotion.

• What is the speaker's main defense against Bart K's critique? 🤔

  The speaker defends their knowledge of acids and hydronium ions (H3O+) by referencing their prior video work and published research to substantiate their understanding. They deny Bart K's claims that they have a misunderstanding, particularly concerning hydrogen ions in biological fluids.
