What two processes of digestion begins in the mouth how do they differ?
Salivary Amylase helps digest starch while in the mouth as a chemical digestion. Chewing is another form of digestion, but its mechanical
Compare mechanical and chemical digestion?
actually the mechanical digestion takes place first in our body that is the whole process of digestion we normally study. where the whole process is of getting things like glucose, minerals, proteins etc.. but the chemical digestion takes place at the cellular level means in the cells that is the break down of glucose in getting energy to work or metabolism of the cells
Where does the mechanical digestion the beginning?
This form of digestion starts in the mouth with the salivary gland witch break down food
Place where only mechanical form of digestion occur?
mouth? because chemiclal form took place in the stomach and if we say mechanical it is something to do with grinding, swallowing and choking. :)
Chewing and churning are examples of what type of digestion?
Chewing is a mechanic digestion as i found out here on WikiAnswers. So i hope i have answered you question those of you who have needed this little bit of information x.what the heck are u talking about?
Is the anus chemical or mechanical digestion?
The anus is not involved in either chemical or mechanical digestion. Its main function is to expel indigestible material out of the body in the form of feces.
Where does physical digestion begin?
This form of digestion starts in the mouth with the salivary gland witch break down food
In what form are carbohydrates absorbed?
Carbohydrates are digested until they are mono or disaccharides and then they are absorbed through the intestinal lining.
Where and how does hydrolysis occur during digestion?
In your mouth, amalyze chemically digests new food through your spit. This is a form of hydrolysis in digestion.
What is the definition of the digestive system?
Digestion is the breaking down of chemicals in the body, into a form that can be absorbed. It is also the process by which the body breaks down chemicals into smaller components that can be absorbed by the blood stream. In mammals, preparation for digestion begins with the cephalic phase in which saliva is produced in the mouth and digestive enzymes are produced in the stomach. Mechanical and chemical digestion begin in the mouth where food is chewed, and mixed with saliva to break down starches. The stomach continues to break food down mechanically and chemically through the churning of the stomach and mixing with enzymes. Absorption occurs in the stomach and gastrointestinal tract, and the process finishes with defecation. (by Wikipedia.com)
Effect of HCl on protein digestion by pepsin and starch digestion by sallivary amylase?
HCl activates pepsinogen to form pepsin, which is the active form of the enzyme pepsin necessary for protein digestion in the stomach. However, HCl does not directly affect salivary amylase. Salivary amylase works optimally at a neutral pH in the mouth before food reaches the stomach, where it begins the digestion of starch into smaller sugars before being inactivated by stomach acid.
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.
