Why do all enzymatic reactions need activation energy? why do all enzymatic reactions need activation energy? energy is required by an enzyme so that it can be reused. energy is needed for the enzyme to find its substrate. energy is required to disrupt a substrate’s stable electron configuration. energy allows only the substrate to bind.

Energy is required to disrupt a substrate’s stable electron configuration.

Explanation:

Activation energy is the energy required to initiate the chemical reaction. Activation energy is always kinetic energy. Activation energy is used to break the existing bonds of the substrate to destabilize it.

Breaking of existing bonds of the substrates creates a transition state which in turn has higher free energy than both reactants and products. Once the transition state is formed, the reaction proceeds towards the formation of the product.

Enzymes serve to lower down the activation energy for the reaction and thereby allow the reaction to occurs at a higher rate even at a normal temperature.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

then that particular organisms become extinct.
