  2. Atmospheric Nitrogen is directly used by plants and animals

  3. Nitrogen is present in Vitamines

  4. All of the above

Show answer
Correct Option: C
Explanation:

The amount of nitrogen in the atmosphere remains fixed. Nitrogen cycle keeps the atmospheric. nitrogen more or less constant. Atmospheric nitrogen cannot be taken directly by plants and animals various steps process are done by microbes to convert it into usable forms. Vitamins contain nitrogen.

  1. Albumin of egg

  2. Polysaccharides

  3. Fat soluble vitamins

  4. Proteins

Show answer
Correct Option: C
Explanation:

Monoglycerides and fatty acids enter absorptive cells in the small intestine through micelles; they leave micelles and recombine into chylomicrons, which then enter the bloodstream. Fat soluble vitamins are absorbed in the same manner as lipids; water soluble vitamins can be directly absorbed into the bloodstream from the intestine.

Vitamins and minerals are together referred as

  1. Energy producing foods.

  2. Body building foods.

  3. Harmful foods.

  4. Protective foods.

Show answer
Correct Option: D
Explanation:

A vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism.
A mineral is a chemical element required as an essential nutrient by organisms to perform functions necessary for life.
 Essential nutrients and minerals cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
 They are present in foods (like leafy or yellow vegetables, citrus fruits, meat, milk, eggs). Food which contains adequate amounts of vitamins, minerals, and high-quality proteins is a protective food. And it also protect against the development of a deficiency disease (as pellagra, beriberi, scurvy). Hence, the vitamins and minerals containing foods are together referred to as protective food.

So, the correct option is 'protective food'.

Which of the following statements is not correct?

biology constitutes of diet role of vitamins functions and principal sources of vitamins and minerals digestive disorders need for nutrients

  1. Amino acids are a product of the digestion of proteins

  2. Vegetable fats contain enough vitamin A and D

  3. Pepsin is produced in the glands in the lining of the stomach

  4. Vitamin C is most plentiful in citrus fruits

Show answer
Correct Option: B
Explanation:

  • The end product of protein digestion is amino acids.
  • The most common source of Vitamin C is citrus fruits.
  • The stomach mucosa’s epithelial lining consists only of surface mucous cells, which secrete a protective coat of alkaline mucus. A vast number of gastric pits dot the surface of the epithelium, giving it the appearance of a well-used pincushion, and mark the entry to each gastric gland, which secretes a complex digestive fluid referred to as gastric juice. Chief cells—Located primarily in the basal regions of gastric glands are chief cells, which secrete pepsinogen, the inactive proenzyme form of pepsin. HCl is necessary for the conversion of pepsinogen to pepsin.
  • Fish oil contains enough vitamin A and D.

So, the correct answer is 'Vegetable fats contain enough vitamin A and D'.
