In chemical digestion are foods physically broken down into smaller pieces by chewing?

Chemical digestion is the process of enzymes and acids breaking the bonds that make up the food. Proteins are broken down into their chemical components by enzymes. Chewing is the mechanical process, aka as mastication, which cuts and grinds the food into smaller particles that are mixed with saliva to form a ball-shaped mass or bolus. The saliva contains an enzyme analaise, which starts the first stage of chemical digestion. This enzyme breaks the long carbon chemical chains that make up starches into simpler compounds called sugars.
The "slimy" bolus then travels down the esophagus through the pyloric valve into the stomach. Here, the strong muscular stomach, together with the hydrochloric acid churns the chyme, mixing it with the acid and the bolus is further reduced in size and chemical complexity. The resulting food-stuff is now called chyme.

What two digestive system occurs in the mouth?
Mechanical and chemical digestion both occur in the mouth (physically chewing and when saliva breaks down food into smaller bits).
How is mechanical digestion is different than chemical digestion?
Chemical digestion uses enzymes and other chemicals to break the bonds in food. Mechanical digestion is basically the teeth grinding the food into physically smaller pieces.
Type of digestion that involves using enzymes and other body acid to break food down into smaller molecules?
Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.
What does chemical digestion in the stomach require?
The process of chemical digestion starts is your mouth! When you start chewing, your saliva helps break down the food as it goes down the esophagus.
What is a physical and chemical change that take place in the digestion of food?
Physical: Chewing to make the food particles smaller. Chemical: Reactions with enzymes to break down the food so the body can use it.
What does mechanical digestion mean?
Mechanical digestion happens in only in 2 of your digestion organs mouth and stomach. Mechanical digestion is the mechanical way you digest your food for example when your eating your teeth are mechanical digesting your food by making your food smaller by chewing on it your not changing your food in any way that only happens chemical digestion is happening.Another example of mechanical digestion is in your stomach when the food is bong to the stomach your stomach is squeezing mushing up the food to make it smaller (your stomach is made out of 3 lairs of mussel's which squeeze in all 3 different direction's).
What is the initial site of mechanical and chemical digestion?
The mouth is the beginning of both mechanical and chemical digestion. Chewing breaks the food into smaller pieces and the saliva wets the food but also adds an enzyme called amylase that begins the digestion of carbohydrates.
How might the chewing of food be related to the rate of chemical reaction digestion that occurs in your body?
Chemical reaction rate is increased by: -increased surface area -increased temperature -increased concentration of reactants -presence of a catalyst Chewing food essentially breaks up large chunks of food into smaller bits, increased total surface area for digestion.
What 2 types of digestion takes place in the mouth?
Mechanical and chemical digestion. In mechanical digestion the teeth breakdown food into smaller pieces and in chemical digestion the salivary glands breaks down the food molecules.
Why is mechanical digestion important for chemical. Digestion?
Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
What is the mechanical digestion that prepares the food for the digestion?
Digestion can be mechanical or chemical. Mechanical digestion is the process of physically (i.e. not involving biochemical enzyme) breaking food down into smaller pieces, creating a greater surface area for chemical digestion to take place. Examples of mechanical digestion include the churning motion of your stomach and obviously, the chewing process of your mouth. Chemical digestion, on the other hand, requires the presences of enzymes to trigger chemical reaction and break the food particles down to simpler substances. Examples include the salivary amylase breaking down sugar, stomach acid and gastric enzymes breaking down proteins, and the lipase breaking down lipids in the small intestine.
Contrast mechanical digestion with chemical digestion and give an example of each?
Physical digestion is, basically, "mashing." The food is ground up (by the teeth), mashed into a paste (by the stomach), and so forth. It's mixed with other foods in the process, but no new molecules are produced. Chemical digestion involves chemical reactions, and new molecules ARE produced. The action of enzymes in saliva, gastric juices, and so forth is a form of chemical digestion.
