Chemical digestion in the stomach

Answer 1

When the stomach churns and squeezes the food this is physical digestion. When the enzymes and hydrochloric acid are added, this is chemical change.

Answer 2

Well chemical digestion is the breakdown of molecules, which is sped up by catalysts known as enzymes. The main component of chemical digestion in the stomach is the gastric juice; it is composed of mucus, hydrocholoric acid (HCl) and pepsinogen.

some formulas for chemical digestion are:

proteins+water-->polypeptides-->peptides-->amino acids

pepsin erepsin

starch+water-->disaccarides-->simple sugars

amylase maltase

fat-->fat droplets+water-->glycerol+fatty acids

bile lipase

p.s The word under the equations are the names of the enzymes that helped the process along. so what is it then

Answer 3

Even before food reaches the stomach, glands in the stomach lining begin to produce digestive juices. One juice, hydrochloric acid, is srong enough to make a hole in the carpet or dissolve metal. The walls of the stomach and other organs are protected. they produce mucus, a slippery material that froms a thick, protective coating inside digestve organs. The stomach also amkes digestive enzymes. some stomach enzymes begin to break down the proteins found in meat, eggs, diry products, and beans. Like the esophagus, the stomach undergoes peristalsis. Waves of the muscle action MASH and churn the food and digestive juices. the food soon becomes a thick soupy liquid called chyme. then it is ready to leave the stomach.

Answer 4

Yes there is! The stomach moves around and breaks up the food in the stomach while the acids in there also chemically break food down. When the stomach is turning without any food it grumbles and tells you that your hungry.

Answer 5

In the stomach, a large sack-like organ, the food is churned and mixed with a strong gastric (mostly hydrochloric) acid. Only partly digested, this mix in the stomach is called chyme.

Additional Information:

However, the digestive process isn't restricted to the stomach. Digestion is accomplished over the full range of the digestive system, beginning in the mouth and ending at the anus.

In the mouth, food is partially broken down by biting and chewing and by the chemical action of salivary enzymes (saliva) that becomes mixed with the food while it is being chewed.

After being swallowed, through the throat, the food enters the esophagus, a long tube with muscular walls, that runs from the throat to the stomach. It uses rhythmic, wave-like motions of its walls (called peristalsis) to force food from the throat to the stomach. This organ gives us the ability to eat or drink even when we're upside-down.

In the stomach, digestion proceeds with the addition of stomach fluids with a churning action.

After the stomach, the chyme moves through the duodenum, the first part of the small intestine. It then moves through the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile, pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine assist in the continuing breakdown of chyme.

The chyme then passes into the large intestine. Here, some of the water and electrolytes (chemicals like sodium chloride) are absorbed from the chyme. Many microbes along the intestines, especially the large intestine, further assist in the digestive process. The first part of the large intestine is called the cecum (the appendix is connected to this). The chyme then travels upward in the ascending colon. The food travels across the abdomen in the transverse colon, and back down the other side of the body in the descending colon, and then through the sigmoid colon.

At the colon, digestion is essentially complete. The remaining material is waste and is temporarily stored in the rectum, from which it is soon excreted via the anus.

Answer 6

in the stomach. enzyme juice dissolves the food after it has been chewed. then the stomach churns and turnes to help dissolve

Answer 7

because I want to

Answer 8

hydrochloric acid
