Abstract
The protonation state of soluble and membrane-associated macromolecules dictates their charge, conformation, and functional activity. In addition, protons (H + or their equivalents) partake in numerous metabolic reactions and serve as a source of electrochemical energy to drive the transmembrane transport of both organic and inorganic substrates. Stringent regulation of the intracellular pH is therefore paramount to homeostasis. Although the regulation of the cytosolic pH has been studied extensively, our understanding of the determinants of the H + concentration ([H + ]) of intracellular organelles has developed more slowly, limited by their small size and inaccessibility. Recently, however, targeting of molecular probes to the organellar lumen together with advances in genomic, proteomic, and electrophysiological techniques have led to the identification and characterization of unique pumps, channels, and transporters responsible for the establishment and maintenance of intraorganellar pH. These developments and their implications for cellular function in health and disease are the subject of this review.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
