WebThe active site of the enzyme can provide a microenvironment with a different pH that facilitates the reaction. Binding of the substrate to the active site can stretch bonds in the substrate that need to be broken. The active site can provide heat from the environment that raises the energy content of the substrate. in and out puppy pattyWebA C=C bond is about 1.5 times as strong as a C=C bond. That would make it vibrate faster than a C-H bond. But µ (C-C) = 6, while µ (C-H) = 0.92. The reduced mass of a C-C pair is about 6.5 times that of a C-H pair. The greater reduced mass makes the C=C bond vibrate much more slowly than a C-H bond. in and out python
