What is the only macromolecule that gets digested enzymatically in the mouth?
There are two that begin to be digested in the mouth. Sugars by amylase and fats by lingual lipase.
Is a chemical digestion occur only in the small intestine is that true or false?
No, digestion begins in the mouth but also occurs in the stomach and small intestine.
Why doesn't the digestion of meat start in the mouth?
The enzymes required to break down fat and lipids (fats) in our diet are found in the stomach/intestines. It would not be efficient to absorb the nutrients from our food that far away from the stomach/intestines.
What is the definition there is no cell specialization and only one opening in this type of digestion?
There is no cell specialization and only one opening in this type of digestion means that some organisms, such as flatworms, don't have a developed digestive system. Every cell is exposed to the digestion process. Also, with these organisms, a single opening doubles as their mouth and anus.
What is the macromolecule of sucrose?
Sucrose contain only glucose and fructose; it is difficult to say that is a macromolecule.The chemical formula is C12H22O11.
Does digestion begin in your stomach?
Correctly, physical digestion begins in the mouth, when foodstuffs are pulverised and mashed up into small pieces, and coated with saliva, to make swallowing easier and to increase it's surface area. This process is completed in the stomach, where food is liquified by strong hydrochloric acid secreted by the gastric glands to make it easy to assimilate. All these processes are classed as physical digestion, but not actual ABSORPTION- this takes place in the small intestines. The only substance absorbed by the stomach is alcohol.
Do the small intestines perform chemical or mechanical digestion?
The only mechanic part of the digestive system of animals are the mouth/teeth or the crop in animals with no teeth.
How does the esophagus perform mechanical digestion?
Peristalsis. The movement of muscles bringing the food to the stomach.
Why is sucrose not a macromolecule?
Sucrose contain only two small units.
What type of food does amylase act on?
starch is broken down by amylase and starch is the only food that its digestion begins in mouth by amylase of salavia.
What mechanical and chemical digestion occurs in the oral cavity?
Chemical Digestion takes place in your mouth Because you have to make it softer by chewing it. While you chew it, your saliva (your spit) breaks it down even smaller! By then, it will be small enough to go to your stomach. Because your stomach can't chew your food.
Does any digestion of food occur in the esophagus?
Yes saliva is used to help turn the food into a substance which is able to slide down the esophagus. Salivary glands produce the saliva in the mouth however; the saliva does help to digest the food slightly in order for it to be moved by peristaltic waves. The main function of the esophagus is to move the food, but it will have been slightly digested.
