Carbohydrate When living organisms are cooled below some critical body temperature, the metabolic reactions within their cells cease to function properly. This malfunction occurs because the activation energy for the reaction is raised enzyme active sites become permanently bound to substrates there is insufficient molecular motion for substrates to interact their enzymes lose the proper three-dimensional shape the activation energy for the reaction is raised enzyme active sites become permanently bound to substrates there is insufficient molecular motion for substrates to interact their enzymes lose the proper three-dimensional shape ANSWER DOWNLOAD EXAMIANS APP
