16.Explain briefly digestion of food in human. Mention all the enzymes that involve in the digestion of food.
Answers
Answer:
the following properties were apart of digestion of food enzymes-
Explanation:
These enzymes include proteases that digest proteins, and nucleases that digest nucleic acids. Examples of digestive enzymes are: Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules
Answer:
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages: the cephalic phase, the gastric phase, and the intestinal phase.
The first stage, the cephalic phase of digestion, begins with gastric secretions in response to the sight and smell of food. This stage includes the mechanical breakdown of food by chewing, and the chemical breakdown by digestive enzymes, that takes place in the mouth.
The first stage, the cephalic phase of digestion, begins with gastric secretions in response to the sight and smell of food. This stage includes the mechanical breakdown of food by chewing, and the chemical breakdown by digestive enzymes, that takes place in the mouth.Saliva contains digestive enzymes called amylase, and lingual lipase, secreted by the salivary glands and serous glands on the tongue. The enzymes start to break down the food in the mouth. Chewing, in which the food is mixed with saliva, begins the mechanical process of digestion. This produces a bolus which can be swallowed down the esophagus to enter the stomach.
The second stage of digestion then begins in the stomach with the gastric phase of digestion. Here the food is further broken down by mixing with gastric acid until it passes into the duodenum, the first part of the small intestine.
The second stage of digestion then begins in the stomach with the gastric phase of digestion. Here the food is further broken down by mixing with gastric acid until it passes into the duodenum, the first part of the small intestine.The third stage begins in the duodenum with the intestinal phase of digestion, where partially digested food is mixed with a number of enzymes produced by the pancreas. Digestion is helped by the chewing of food carried out by the muscles of mastication, the tongue, and the teeth, and also by the contractions of peristalsis, and segmentation. Gastric acid, and the production of mucus in the stomach, are essential for the continuation of digestion.
Peristalsis is the rhythmic contraction of muscles that begins in the esophagus and continues along the wall of the stomach and the rest of the gastrointestinal tract. This initially results in the production of chyme which when fully broken down in the small intestine is absorbed as chyle into the lymphatic system. Most of the digestion of food takes place in the small intestine. Water and some minerals are reabsorbed back into the blood in the colon of the large intestine. The waste products of digestion (feces) are defecated from the anus via the rectum.
Explanation:
1.An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
2.The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
3.Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine.
But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
Types of enzymes
There are three main types of digestive enzymes. They’re categorized based on the reactions they help catalyze:
1.Amylase breaks down starches and carbohydrates into sugars.
2.Protease breaks down proteins into amino acids.
3.Lipase breaks down lipids, which are fats and oils, into glycerol and fatty acids.
Enzymes are essential for healthy digestion and a healthy body. They work with other chemicals in the body, such as stomach acid and bile, to help break down food into molecules for a wide range of bodily functions.
I Hope it helps you ☺️
