Stomach acid helps break down food because it contains enzymes, which are like "cutting tools" for certain food particles.
The acid itself does not break the food down, it is the biological enzymes floating around inside the acid that break the food down.
The only reason the stomach is acidic is because the enzymes in the stomach work more effectively at a lower pH.
Hydrochloric Acid (HCl)
stomach turns, constantly moving the acid in it. Acid breaks down the food to be absorbed into the stomach walls. Whatever doesn't get absorded keeps going down the line.
pepsinogens when pumped into the stomach and exposed to an acid environment form pepsin. pepsin is a protease breaking proteins down into amino acids.
It is most likely the the stomach since the intestines do not break down food. The stomach is filled with extremely strong acids that are powerful enough to dissolve razor blades whole. The food drops into our stomachs and immediately breaks down. Then the stomach passes what is left through the Pyloric Sphincter (the wall passage between stomach and small intestine). The small intestine then absorbs all the nutrients through the villi (small hairlike cells on the inner intestine walls). Once the food reaches the large intestine, bile is added to the food, turning it into our stool, while absorbing liquids and salts from the product. Then the food leaves our bodies, only so we can obtain more.
Yes, lactase can definitely break down cellulose. In fact, when the lactase works to break down the cellulose, it breaks the cellulose down into two different monomers.
Think of a cell as a factory. The nucleus is the "boss", and lysosomes are like the "clean-up" crew after all the work has been done. they go around in the cell breaking down wastes; getting rid of it.
No, in the stomach it is an Acid that helps break down food.
Acid breaks down the food in the stomach. Pepsin is the enzyme that breaks down the proteins from the food, in the stomach. Highly acidic pH helps to break down the food.
The stomach mixes the food with acid which helps to break down the proteins and complex carbohydrates so the body can utilize them.
Saliva helps the mouth to break down the food, but what digests the food is fiber, and stomach acid.
It uses very strong acid called stomach acid to break it down
to break down the food
by the acid
Stomach acid.
Pepsin, which is used to break down proteins, cannot work unless it is in an acid environment. Due to this fact, the stomach secretes both pepsin and hydrochloric acid to digest the protein in a meal.
Stomach acids are in part Hydrochloric Acid, HCl.
The correct answer is stomach acid
The acid helps to break down food as part of the digestive process. It also kills many bacteria that we ingest, reducing the chances of infection.
