Cell Respiration State that oxidation involves the loss of electrons
... In the Krebs cycle and glycolysis, pairs of hydrogen atoms are removed from the respiratory substrates. Oxidised NAD is converted into reduced NAD, except in the Krebs cycle, where FAD is reduced instead. Hydrogen atoms or their electrons are transported along a series of carriers in the final stage ...

Crystal Field Theory: Octahedral Complexes
... There are only 4 ligands in the tetrahedral complex and hence the ligand field is roughly 2/3 of the octahedral field. The direction of ligand approach in tetrahedral complex does not coincide with the d-orbitals. This reduces the field by a factor of 2/3. Therefore Δt is roughly 2/3 x 2/3 = 4/9 ...
