Which one of the following is not correctly matched?

Read thoroughly the following statements concerning with the assimilation of food. Identify true and false statements and choose the correct option from the given codes I. Conversion of amino acid into glucose and then into fat is irreversible reaction II. During the conversion of amino acids into glucose, amino group of amino acids is removed III. Excess of amino acids are converted into glucose and fats and thus are stored IV. Excess of simple sugars are stored in the liver and kidny. The process is known as glycogenolysis V. Process of gluconeogenesis occurs in the kidney and striped muscles

Choose the odd one out with respect to
organ/cell where synthesized.

Go through the following statements regarding the absorption of nutrients. Identify wheather they are true or false then choose the correct option accordingly
I. Absorption of monosaccharides, alcohol, some water and medicines like aspirin occurs in the stomach
II.Fatty acids cannot be absorbed directly
III.Transport of water depends upon the osmotic gradient
IV.Maximum absorption of water (90%) takes place in the small intestine
V. Large intestine and mouth are not the site of absorption

Vitamin- $\mathrm{B}_{12}$ is absorbed primarily in the stomach

In human beings, digestion of carbohydrates starts from the mouth. How much percentage of it is digested in the mouth?

Which one of the following combination of vitamins are synthesised by bacteria?

The cells, which destroy worn out white and red blood cells, bacteria and micro-organisms passing from the liver are

Chief cells of gastric glands are  also known as

Assertion: Bile is essential for the digestion of lipids

Reason: Bile juice contains bile salts required for emulsification of fats.

Identify the correct statement

What is gastroporesis?

What are the narrow extensions of the pulp cavity?

Aggregates of lymphoid tissue present in the distal portion of the small intestine are known as

Seggregate the following statements into true and false category. Choose the right answer from the codes given below
I. Mucosal epithelium has goblet cells which secrete mucous and helps in lubrication
II. Mucosa forms gastric glands in the stomach and crypts in between the bases of villi in intestine
III. Cells lining the villi has brush border or microvilli
IV. All the four basic layers in the wall of gut never shows modification in different parts of the alimentary canal

If pancreas is removed, the compound which remain undigested is

Identify a disorder which is not commonly associated with the digestive system.

The amount of bile released is proportional to the amount of

Which of the following animals eats its prey?

A balanced diet lacks

Trypsinogen present in pancreatic juice is first activated with the help of

Improper balance diet may cause

Deficiency of Vitamin-${B_{12}}$ causes

As you know that HCl is highly acidic (1.5 to 2.0 pH) in the stomach, however, the epithelium of the mucosa remains unaffected/undissolved. Why?

Identify the correct statement with reference to human digestive system

‘Digestion’ word means

Go through the following statement regarding the physiology of digestion and identify whether they are true or false Choose an appropriate option from the codes given below I. Largest variety of hydrolases are present in omnivores, while the herbivores, generally lack digestive enzymes II. Digestive enzymes are of four types namely, amylase, proteinases, lipases and nucleases III. Proteinases are also known as proteases which are released in the active form because the proteins, either cellular or extracellular, all are hydrolysed by them in the absence of food IV. Hydrolases and cholecystokinin are secreted by the exocrine part of pancreas

Assertion: Vitamins are essential for healthy life.

Reason: Vitamins regulate metabolism.
