The decoherence mechanisms likely to dominate biological setting, was analyzed. It was observed that Tegmark's commentary is not aimed at an existing model in the literature but rather at a hybrid that replaces the superposed proteins conformations of the orch. Tegmark's formulation yields decoherence times that increase with temperature contrary to well established physical intuitions and the observed behavior of the quantum coherent states. The decohering effect of radiative scatters on microtubule quantum states is negligible.
