Primes¶

Activation Energy
- It separates two states (unreacted and reacted; dormant and active; fragmented and mobilized) and names the work required to cross between them.
  This sourceFoundational paper on transition state theory: formalizes the barrier-threshold-transition structural pattern via the activated complex in quasi-equilibrium with reactants. SUPPORTS the structural-signature claim that the pattern was formalized in Eyring's transition state theory.
  
  Supported in partVerified against the publisher's abstract
  
  Eyring's abstract establishes the activated complex and its decomposition rate, giving the two-state barrier frame but not naming the activation energy as the work required to cross between states.
  
  “The probability of the activated state is calculated using ordinary statistical mechanics. This probability multiplied by the rate of decomposition gives the specific rate of reaction.”
  From the publisher's abstract.

Hidden Path and Barrier Crossing
- This quantum-mechanical contribution is particularly important in enzymes like monoamine oxidase, alcohol dehydrogenase, and methylamine dehydrogenase, where hydrogen or deuterium kinetic isotope effects (H/D KIE values >> 1) directly indicate tunneling.

  Supported in partVerified against the publisher's abstract
  
  Eyring's abstract supplies the chemistry side of the frame - rates set by an activated complex on a constructed potential surface, with features hidden from simple kinetic theory - but names no wavefunction or tunneling parameter.
  
  “The occurrence of quantized vibrations in the activated complex, in degrees of freedom which are unquantized in the original molecules, leads to relative reaction rates for isotopes quite different from the rates predicted using simple kinetic theory.”
  From the publisher's abstract.

Saddle Point
- Theoretical ecology characterized coexistence equilibria by which directions are stable, an analysis identical in form to dynamical-systems saddles, and chemistry found that reaction transition states are saddles of the potential-energy surface, the same geometry driving Eyring's transition-state theory.

  Eyring's own abstract frames absolute reaction rates from potential-energy surfaces and an activated complex, but never says the transition state is a saddle point of that surface.
  
  “The calculation of absolute reaction rates is formulated in terms of quantities which are available from the potential surfaces which can be constructed at the present time. The probability of the activated state is calculated using ordinary statistical mechanics.”

Verification¶

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Read against the text for 3 of 3 citations: 3 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
