Mechanical digestion breaks down large food particles into smaller ones, increasing the surface are to volume ratio. However, polymers present in food particles require a very long time to break down at body temperature - for this reason, the process requires a catalyst. The presence of digestive enzymes speed the rate of digestion up by over 1 million times, facilitating the breaking of chemical bonds and requiring a lower activation energy to initiate the reaction.
