The answer is <span>Chemical digestion involves the breaking down of food with enzymes; </span><span>mechanical digestion is breaking down food by chewing and tearing with teeth. 

Mechanical digestion means breaking down food mechanically. By chewing and tearing with teeth, food breaks down into smaller parts and no enzymes are used. Chemical digestion means breaking down food in a chemical manner. This is achieved by secreting enzymes, which break down chemical bond between food molecules.</span>

 The Best answer to the question stated above is "Chemical digestion involves the breaking down of food with enzymes; 
mechanical digestion is breaking down food by chewing and tearing with teeth. "

Mechanical digestion prepares food for chemical digestion.  It involves the chewing and mixing food with saliva, churning of food in the stomach, segmentation of intestines rhythmic local constrictions of intestine, causes mixing improves absorption. On the other hand c<span>hemical digestion breaks down complex food molecules into chemical building blocks, enzymes secreted into alimentary canal lumen.</span>

During an enzymatic reaction, a molecule of binds to the enzyme and is broken down into one or more molecules of____, which are
Ugo [173]

During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.

<h3>What is substrate and product ?</h3>

While products can be produced at the end of the reaction, substrates are the reaction's initial raw material. The distinction between a substrate and a product is that a substrate is the substance used to initiate a chemical reaction, whereas a product is the compound formed when the reaction is finished.

<h3>What do you mean by enzymatic reaction ?</h3>

In an enzyme reaction, the free enzyme E binds to its substrate S to form the enzyme-substrate complex (C1), which is then catalyzed into the enzyme-product complex (C2), from which the free enzyme and product P are released: S + E ↔ C1 ↔ C2 → P + E. This is known as the "lock-and-key" model in enzymatic reactions. The great majority of cellular reactions are represented by this paradigm.

Thus from the above conclusion we can say that during an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
