Digestion takes place outside of the cell's cytosol. For example within lysosomes, in a digestive tract or in a digestive cavity. This is because:

In human beings, digestion takes place outside the cells in alimentary canal is called ____.
Adi S.
Drag and drop each characteristic to the correct class of macromolecule. Enzymes break down into amino acids in the small intestine. Micelles form and aid lipid breakdown. Digestion begins in the mouth. Major enzyme is lipase. Emulsification breaks larger droplets into smaller ones. Amylase breaks down starch in the mouth and small intestine. Uptake via active transport and facilitated diffusion. Chymotrypsin. Trypsin. Digestion occurs almost entirely in the small intestine. Acidity in the stomach stops starch digestion. Broken down into peptide fragments in the stomach. Carbohydrates. Proteins. Fats.
The vast majority of fat digestion occurs in the portion of the GI tract. It begins when triglycerides are emulsified by from the gallbladder. The bile was originally made by the and is made of cholesterol with a small amino acid attached. This substance from the gall bladder coats the fat and forms a lipid droplet called a . An enzyme called is then released by the and that enzyme will break down triglycerides into monoglycerides, , and . This lipid droplet (with fat soluble vitamins and cholesterol included with the triglyceride break down products) will cross into the villi cell. Once in the cell, the long chain fatty acids and recombine to form triglycerides and these join with fat soluble vitamins, proteins, and to form the , which is one of several lipoproteins that transport lipids in the blood. The chylomicron will move into the system and eventually enter the blood stream. In contrast to the above mentioned lipids, the glycerol and the are smaller compounds and can move directly into the cell and on to the .
