ATP/ADP Oscillation

ATP/ADP oscillation is the universal τ-categorical energy-currency cycle of life: a τ-categorical oscillation between ADP+P_i (low-energy) and ATP (high-energy) states that couples energy-yielding processes (catabolism) to energy-requiring processes (anabolism, transport, signaling).

τ-Definition

ATP/ADP oscillation is the universal τ-categorical energy-currency cycle of life: a τ-categorical oscillation between ADP+P_i (low-energy) and ATP (high-energy) states that couples energy-yielding processes (catabolism) to energy-requiring processes (anabolism, transport, signaling).

Categorical invariant. Two-state τ-categorical oscillation: ATP ⇌ ADP + P_i with free-energy gap ΔG ≈ -7 kcal/mol per hydrolysis under cellular conditions.

Empirical Correlate

Biomarker: Cellular [ATP] ≈ 1-10 mM; [ADP] ≈ 0.1-1 mM; ATP/ADP ratio ≈ 10:1; free-energy of ATP hydrolysis ΔG ≈ -7 kcal/mol (under physiological conditions, with [Pi]).

Measurable range: ATP turnover ~10⁷ molecules/cell/s in active cells; whole-body ATP consumption ~70 kg/day in adult human (recycled, not synthesized de novo); brain alone uses ~20% of ATP.

Observation method: Luciferase-based ATP assay (luminescence), HPLC, ³¹P NMR (in-vivo), fluorescence biosensors (Perceval, ATeam), mass spectrometry of nucleotide pool.

Calibration anchor: LG-Y02-kinetic-pseudoscalar-channel

Anchor chain:

  1. VI.L18 chirality channel
  2. ATP's D-ribose sugar handedness (inherited from K_χ)
  3. stereospecificity of every ATP-binding enzyme
