The gastric phase of gastric secretion is triggered by the:
Anvisha [2.4K]

Answer:

The entry of food into the stomach.

Explanation:

Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.

The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.

Match each molecule with the group of carbohydrates it belongs to
beks73 [17]

Answer:

If you are referring to the image below, the answers would be:

Monosaccharides:

  • Galactose
  • Glucose
  • Ribose
  • Deoxyribose
  • Glyceraldehyde
  • Fructose

Disaccharides:

  • Maltose
  • Sucrose
  • Lactose

Storage Polysaccharides:

  • Starch
  • Glycogen

Structural Polysaccharides:

  • Chitin
  • Cellulose
  • Amylopectin
  • Amylose

Explanation:

Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)

Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.

Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.

Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.

Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.

New genes created by genetic engineering produce brand new proteins called "novel" proteins. All proteins have the potential to
ira [324]

Answer:

Novel proteins may cause allergic reactions. Moreover, protein may also suffer folding when they are introduced into the plant, thereby converting them in potential allergens.

Explanation:

Genome engineering techniques are those procedures used in molecular biology to design genetically modified organisms by altering their genomes.

All proteins have the potential to cause allergic reactions. For example, celiac disease is an autoimmune disorder caused by an allergic reaction to the proteins of cereals; however, only a small fraction of proteins is associated with autoimmune diseases. There are many methods to study the potential of protein allergens, the enzyme-linked immunosorbent assay (ELISA) is currently the technique most widely used for this purpose by detecting antibody-antigen interactions (i.e., interactions between molecules of the immune system and antigen allergens).
