What is it called when your stomach digests itself?
Autodigestion refers to the process where the stomach lining is damaged by its own digestive acids and enzymes, leading to inflammation or ulcers. This can occur due to a disruption in the stomach's protective mucosal barrier, causing the stomach to essentially digest itself.
What gives rise to lysosomes and vesicles?
Golgi apparatus gives rise to both lysosomes and vesicles. The most likely explanation for the bad taste of meat that has freezer burn from repeated freezing is the destruction of lysosomes and resultant autodigestion.
How do lysosomes work?
vacuoles basically have the same functions as vesicles therefore, in plant cells, when lysosomes are fused with the vacuole, the contents within the vacuole are digested by lysosomes' hydrolytic enzymes into the simpler subunits. Remember that vacuoles not only store H2O, sugar and salt, but also pigments and toxic molecules. The digested contents are now simpler molecules that are released into the cytoplasm. Also, normal rejuvination occurs when parts of a cell are digested within its own lysosomes (autodigestion).
Which cell component is capable of cellular autodigestion when it is released during cell injury?
Lysosomes are the cell components responsible for cellular autodigestion when they are released during cell injury. These organelles contain digestive enzymes that can break down various biomolecules. When lysosomes rupture, their enzymes can leak into the cytoplasm, leading to the degradation of cellular components and ultimately contributing to cell death. This process is often associated with conditions like necrosis.

Why pancreas is not digested by its own enzymes?
The acinar cells of the pancreas secrete proteolytic enzymes as zymogens or proenzymes. These enzymes are in their inactive form and must be activated by something else. One of these enzymes, trypsinogen, is activated by enterokinase found in the cells that make up the duodenum wall. Once activated to trypsin, it activates the other digestive enzymes.
What sustance coats and protects the inside of the stomach?
The stomach is protected by the epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa. Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process. This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment.
How could the overuse of antacids inhibit protein digestion?
Antacids neautralize the normal stomach acid causing the pH to rise. When pH in the stomach rises above 4, Pepsin (an ezyme that works to break down protein into smaller pieces so they can later be broken down into amino acids) is decreased or stops. And without pepsin the protein isn't broken down thus inhibiting protein digestion.To understand this, you need to know that the digestion of proteins starts in the stomach with the help of digestive enzymes, mainly pepsin.Pepsin is secreted in an inactive precursor form, called pepsinogen (this is to prevent the stomach cells that secrete pepsin from undergoing autodigestion.)In the acidic environment of the stomach (pH
Why is it important that trypsin cuts only specific peptide bonds?
Trypsin cuts only specific peptide bonds (after lysine or arginine residues) to produce peptides of optimal length for downstream analysis or protein identification. This specificity ensures accurate protein digestion and minimizes the generation of peptides that are too short to provide useful information or too long to be effectively analyzed.

vacuoles basically have the same functions as vesicles therefore, in plant cells, when lysosomes are fused with the vacuole, the contents within the vacuole are digested by lysosomes' hydrolytic enzymes into the simpler subunits.

Emzymes that are required for the digestion of food in the stomach?
Pepsin is a protease enzymes released into the stomach. There is more mechanical breakdown too by the stomach muscles. If you take plant enzymes, most plant enzymes are quite stable in the stomach environment and go to work. This gives the plant enzymes an edge on digestion over animal/pancreatic enzymes. Plant enzymes can be working on food for at least an hour before the food proceeds to the small intestine.Once the food enters the small intestine, plant enzymes continue to work. At this point, any pancreatic or animal enzymes kick in. It is at this point that your naturally produced pancreatic enzymes are released by the pancreas. Some enzymes are released by the small intestine lining as well.The enzymes from the small intestine include:lactase (breaks down milk sugar),DPP IV (breaks down milk protein and other protein bonds), anddissacharrides (breaks down some starches and sugars).
How is the stomach protected from hydrochloric acid?
Your stomach, if you want to be technical about it, is a "crescent-shaped hollow organ" about the size of a large melon. The average adult stomach holds about three quarts (three liters) of fluid. Your stomach is made up of a variety of layers, including: * The serosa - the outer layer that acts as a covering for the other layers. * Two muscle layers - the middle layers that propel food from the stomach into the small intestine. * The mucosa- the inner layer made up of specialized Cells including parietal cells, g-cells and epithelial cells. Parietal cells produce hydrochloric acid, a strong acid that helps to break down food. The acid in your stomach is so concentrated that if you were to place a drop on a piece of wood, it would eat right through it. The g-cells produce gastrin, a hormone that facilitates the production of hydrochloric acid by the parietal cells. The stomach is protected by the epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa. Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process. This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment. In some individuals, due to impairments in blood supply to the stomach, or to overproduction of acid, this defense system does not work as well as it should. These people can get gastric ulcers. There are also specific bacteria, called Helicobacter pylori, that may cause impairment of the stomach's defenses and can also be responsible for ulcers.
