When we ingest large molecules such as lipids, carbohydrates, and proteins, they must undergo catabolic reactions whereby enzymes

Question

b.secretion: it is the phenomenon of release of enzyme, hormones and some salt in case of digestion.

Ms. Juana Fadel · Accepted Answer

A. chemical digestion: it the type of digestion which occurs due to enzymes start right from the mouth with help of amylase enzyme. some of it occurs in stomach, but the major part complete in small intestine.b.secretion: it is the phenomenon of release of enzyme, hormones and some salt in case of digestion.c. mechanical digestion: it is that type of digestion which occurs due to teeth, in which large food is broken down into small pieces to form bolus.d. absorption: it is the process in which food molecules are absorbed in villi in intestine. the correct option is a (chemical digestion).

Ms. Juana Fadel · Answer

Chemical DigestionExplanation:Under digestion, chewing is considered to be half the battle. After food is done travelling from our mouth to our digestive system, the digestive enzymes tend to brake it down and thus turn it into several smaller nutrients which are further absorbed by our body.  This breakdown of food through series of reaction is referred to as a chemical digestion.

Ms. Juana Fadel · Answer

metabolism Explanation: catabolism consists of a series of metabolic processes, which involves the breaking down of large molecule of eg, carbohydrate, lipids, proteinsetc, into smaller moleciles that produce energy for the body to use.

Ms. Juana Fadel · Answer

D. chemical digestionExplanation:In chemical digestion, large food molecules are broken down into smaller particles thanks to the action of enzymes present in the digestive juice, undergoing changes in their chemical composition.Chemical digestion is a process that occurs with the action of enzymes. It starts in the mouth with the action of the enzyme amylase, which is present in saliva and digesting starch. In the stomach, there is the action of gastric juice, consisting of hydrochloric acid and the enzyme pepsin, which acts on protein digestion.  In the small intestine, the food undergoes the action of substances produced by the pancreas (alkaline substance containing trypsin and chymotrypsin, enzymes that act on proteins) and by the liver (bile, which contains salts that act on the digestion of fat, is produced by liver but is stored and concentrated in the gallbladder).
