If for some reason the parietal cells of the gut epithelium become partially nonfunctional, what is likely to happen
-
Pancreatic enzymes, specially trypsin and lipase will not work efficiently
-
Proteins will not be adequately hydrolysed by pepsin to proteoses and peptones
-
pH of stomach will fall abruptly
-
Steapsin will not be effective
The enzyme that is not present in succus entericus is
-
Maltase
-
Nucleases
-
Nucleosidase
-
Lipase
Cellulose in our food passes out undigested.
-
True
-
False
Cellulose falls into the category of indigestible carbohydrates known as dietary fibre. Humans don't have an enzyme to digest cellulose.
Digestion of food occurs as a result of
-
hydrolysis
-
oxidation
-
polymerization
-
reduction
- The digestion process depends upon hydrolysis to provide the biochemical reactions that break down food.
- The digestive tract secretes enzymes, such as proteases, carbohydrases, nucleases and lipases that, along with water, catalyze the hydrolysis that releases various nutrients. Hence, the Digestion of food occurs as a result of hydrolysis.
Choose the correct answers from the alternatives given.
Most chemical digestion occurs in the
-
stomach
-
liver
-
duodenum
-
large intestine
Enteropeptidase is an enzyme produced by the cells of the duodenum and is involved in the digestion in humans and other animals. Enteropeptidase converts trypsinogen (a zymogen) into its active form trypsin, resulting in the subsequent activation of pancreatic digestive enzymes
Most digestive systems have regions for.......... food
-
transporting
-
processing
-
storing
-
all of these
The digestive system plays an important role in the absorption of nutrients into the body. It takes the food we ingest, breaks it down mechanically and chemically in the mouth and stomach. It then absorbs nutrients, fats, proteins, and water in the intestines before eliminating the waste through the rectum
Which of the following is not produced in the stomach?
-
Sodium hydrogencarbonate
-
Gastrin
-
Hydrochloric acid
-
Pepsinogen
- The stomach produces gastrin, hydrochloric acid and pepsinogen.
- G-cells in the stomach releases gastrin in response to distension of the antrum. This, in turn, causes an increase in the secretion of HCl from the parietal cells or oxyntic cells, which kills or inhibits bacteria and provides the acidic pH for the proteases to work and pepsinogen is released from chief cells in the stomach called zymogenic cells or peptic cells.
- Pepsinogen, inactive form of the enzyme in presence of hydrochloric acid activates into the active form, pepsin. Pepsin breaks down proteins into polypeptides. Hence, sodium hydrogen carbonate is not produced in the stomach.
Disorders of digestive system
In which of the following order, the process of digestion proceeds?
-
Digestion $\rightarrow$ Ingestion $\rightarrow$ Absorption $\rightarrow$
Assimilation $\rightarrow$ Egestion -
Digestion $\rightarrow$ Ingestion $\rightarrow$ Assimilation $\rightarrow$ Absorption $\rightarrow$ Egestion
-
Ingestion $\rightarrow$ Digestion $\rightarrow$ Assirhilation $\rightarrow$ Absorption $\rightarrow$ Egestion
-
Ingestion $\rightarrow$ Digestion $\rightarrow$ Absorption $\rightarrow$ Assimilation $\rightarrow$ Egestion
Which of these is a part of your digestive system?
-
Stomach
-
Pancreas
-
Rectum
-
All of the above
All of these choices are a part of your digestive system. Your digestive system has many other associated organs including the small intestine, large intestine, and liver. The stomach is an area of food digestion. The pancreas releases hormones that affect the digestive process. The rectum is the last place you store you food before the process of elimination (pooping).

In Paramecium, the phenomenon of cyclosis is associated with
-
digestion
-
excretion
-
locomotion
-
reproduction
Cyclosis is the movement in the fluid in the cytoplasm where the proteins and nutrient in the cytoplasm get digested.
