Rennin is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. It is widely used in the production of cheese. Lactase is an enzyme produced by many organisms. Lactase can be purchased as a food supplement, and is added to milk to produce "lactose-free" milk products. Lactase is the enzymes that splits lactose (milk sugar) into glucose and galactose. The enzymes necessary to break down and digest milk (rennin and lactase) are all gone by the age of three in most humans.
Which of the following processes is helped by bile salts?
-
Nucleic acid $\overset{Nuclease}{\rightarrow}$ Nucleotides $\overset{Nucleotidase}{\rightarrow}$ Nucleosides $\overset{Nucleosidase}{\rightarrow}$ Sugars + bases
-
Sucrose $\overset{Sucrase}{\rightarrow}$ Glucose + Fructose
-
Fats $\overset{Lipase}{\rightarrow}$ Diglyceides $\overset{Lipase}{\rightarrow}$ Monoglycerides
-
Proteins, peptones, proteoses $\xrightarrow[Carboxypeptidase]{Trypsin/Chymotrypsin}$ Dipeptides
The correct answer is (c).
Digestion of food
Which of the following match is correct?
-

Which reserve a starving man first consumed?
-
Fat
-
Protein
-
Glycogen

Vitamin
Starvation mode is a state in which the body is responding to prolonged periods of low energy intake levels. The body responds to reduced energy intake by burning fat reserves and consuming muscle and other tissues. Specifically, the body burns fat after first exhausting the contents of the digestive tract along with glycogen reserves stored in muscle and liver cells. After prolonged periods of starvation, the body will utilize the proteins within muscle tissue as a fuel source.
The digestion of cellulose in rabbit and other herbivorous mammals takes place in
-
Vermiform appendix
-
Colon
-
Caecum

Ileum
Hindgut fermentation is a digestive process seen in monogastric herbivores, animals with a simple, single-chambered stomach. Cellulose is digested with the aid of symbiotic bacteria. The microbial fermentation occurs in the digestive organs that follow the small intestine: the large intestine and caecum.
Choose the wrong enzymatic reaction.
-
Sucrose $\overset{Invertase}{\rightarrow}$ Glucose + Fructose
-
Lactose $\overset{Lactase}{\rightarrow}$ Glucose + Fructose
-
Pepsinogen $\overset{HCI}{\rightarrow}$ Pepsin
-
Maltose $\overset{Maltase}{\rightarrow}$ Glucose + Glucose
The correct answer is (b).
Sucrase is an enzyme found in:-
-
saliva
-
gastric juice
-
intestinal juice
-
pancreatic juice
Sucrase enzymes are located on the brush border of the small intestine. The enzymes catalyze the hydrolysis of sucrose to fructose and glucose. The sucrase enzyme invertase, which occurs more commonly in plants, also hydrolyzes sucrose but by a different mechanism
