Carbohydrates and proteins are digested in the stomach. Carbs require several enzymes to be digested, such as the enzyme salivary amylase (secreted in the mouth); digestion ultimately occurs at the level of the stomach. Proteins are also digested in the stomach, but require a general class of enzymes called proteases in order to be digested. Lipids are digested in the duodenum, the first portion of the small intestine. The secretion of lipase enzymes is necessary to complete this task.

What nutrients are absorbed from the digestive tract directly into the blood?
Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed from the digestive tract directly into the blood.
What enzymes are secreted in an earthworm's digestive tract?
ANSWERAnimals digest their food. The proteins carbohydrates and fat in food. are broken down into simple molecules.
What are carbohydrates fats and proteins broken down to in the small intestine?
Carbohydrates and fats are broken down in the digestive tract into the simple sugars, glucose, fructose, and galactose. The latter two can be converted by the body into glucose, which is distributed throughout the body via the bloodstream and is broken down into Carbon Dioxide and water in the mitochondria of cells. Proteins are broken down into their constituent amino acids, which are used to assemble new proteins throughout the body.
Do food that passes through the digestive tract becomes less complex?
Yes. It is broken down into its comprising proteins, starches, carbohydrates, minerals, vitamins, etc...
Do enzymes in the digestive tract catalyze hydrolysis reactions?
enzymes catayze chemical reaction where Eva the substrate and active site meet wheather that be in you mouth stomach , larger /smaller intesine or lower gut of whitch the biological enzymes are found.
What are the lipoproteins that carry absorbed lipids from the intestinal tract to the bloodstream?
Chylomicrons
What are the lipoproteins that carry absorbed lipids from the intestinal tract to the bloodstream called?
Chylomicrons
In biology Where food is digested the food?
Food is digested in the gastrointestinal tract, starting in the mouth where enzymes begin breaking down carbohydrates. In the stomach, acids and enzymes further break down proteins. The majority of nutrient absorption takes place in the small intestine, where enzymes from the pancreas and bile from the liver help break down fats, proteins, and carbohydrates into molecules that can be absorbed by the body.
How are chylomicrons metabolized?
Lipids are fats, that together with carbohydrates and proteins make up the main parts of cells in organic life. They are a fuel source. Cholesterol is a lipid. Fat takes longer to break down in the intestinal tract because it does not break down in water. The pancreas secretes an enzyme called lipase that helps to break the fat molecules down into smaller molecules to ease digestion and absorption by the body.
When dietary proteins undergo hydrolysis in your digestive tract what are they turned into?
Bile
Why does the influenza virus specifically infect cells of the respiratory tract?
by the spikes made of protein which are inserted into the lipid membrane of the cell.
What do undigested substances include?
Undigested substances can include dietary fiber, plant cell walls, certain fats, and undigested nutrients such as proteins and carbohydrates. These substances can pass through the digestive tract without being broken down and absorbed by the body.
