Riboflavin vitamin is:

A
B$$_{1}$$

B
B$$_{2}$$

C
B$$_{12}$$

D
B$$_{6}$$

Solution

Riboflavin is vitamin B$$_{2}$$. It is water soluble, which means it is not stored in the body. It is important for body growth and red blood cell production and helps in releasing energy from carbohydrates.

Option B is correct.
Question 2
1 / -0

Which disaccharide is present in milk?

A
Maltose

B
Galactose

C
Sucrose

D
Lactose

Solution

Milk contains lactose. You must have heard of milk containing lactic acid, which is formed by the fermentation of lactose by bacteria.
Question 3
1 / -0

Which of the following is true about vitamins?

A
Vitamins in the humanbody are needed in large amounts.

B
Vitamins are secreted by ductless glands.

C
Vitamins are synthesized by an organisms.

D
Vitamins A,D,E and K are fat soluble whereas vitamins of the B group and vitamin C are water soluble

Solution

Vitamins $$ A,D,E$$ and $$K$$ are fat soluble whereas vitamins of the $$B$$ group and vitamin $$C$$ are water soluble vitamins.

Fat soluble vitamins are usually absorbed in fat globules that travel through the lymphatic system of the small intestines and then circulates within the body. While water soluble vitamins are directly absorbed through the intestinal wall into the body.

Other statements are incorrect.

Option D is correct.
Question 4
1 / -0

Vitamin B$$_{1}$$ is known as:

A
ascorbic acid

B
carotenoids

C
thiamine

D
pyridoxine

Solution

Vitamin $$B_1$$ is known as thiamine. It is a water soluble vitamin of B complex. It is important in carbohydrate (sugar and starch) metabolism, maintenance of normal growth, and transmission of nerve impulses.
Question 5
1 / -0

An example of a disaccharide is:

A
Glucose

B
Ribose

C
Cellulose

D
Lactose

Solution

Lactose is made of 1 unit of glucose and 1 unit of galactose. So, it is a disaccharide.
Question 6
1 / -0

Ergocalciferol is name of vitamin:

A
$$A$$

B
$$B$$

C
$$C$$

D
$$D_2$$

Solution

Ergocalciferol is name of vitamin $$D$$.

This vitamin is essential for absorption of calcium and phosporus in the body.

It is used to treat and prevent bone disorders (such as rickets, osteomalacia). Vitamin D is made by the body when skin is exposed to sunlight.

Ergocalciferol is name given to vitamin $$D_2$$.

Option D is correct.
Question 7
1 / -0

Relation between amino acids and proteins is similar to the one between:

A
nucleotides and nucleic acids

B
RNA and DNA

C
Glucose and Fructose

D
Glucose and Mannose

Solution

Proteins are made up of monomeric amino acid units, and thus, called as building blocks of proteins. Similarly, nucleic acids are made up of nucleotides as the monomeric units, and thus, called as building blocks of nucleic acids.
Question 8
1 / -0

N- Glycoside bond connects

A
Sugar , base

B
Sugar , Sugar

C
Base , base

D
Phosphate , ester

Solution

N- Glycoside bond connects sugar with base. It is a type of carbohydrate protein covalent linkage between a sugar and side chain amide.
Question 9
1 / -0

The source of pyridoxine is:

A
cereals

B
meat

C
yeast

D
all of the above

Solution

The source of pyridoxine are cereals, meat and yeast.

Pyridoxine (vitamin $$B_6$$) is found naturally in a lot of foods, but some of the best sources are fish, beef liver, meats, potatoes, yams and other starchy vegetables, eggs and non-citrus fruit.

Fortified cereal is also a great source of vitamin $$B_6$$. Most multivitamins also contain $$B_6$$.

Option D is correct.
Question 10
1 / -0

Which of the following is not a sugar?

A
Sucrose

B
Glucose

C
Fructose

D
All are sugars

Solution

Sucrose, glucose and fructose all are sugars. Glucose and fructose are monosaccharides and sucrose is a disaccharide of the two combined with a bond. Glucose and fructose have the same molecular formula $$(C_6H_{12}O_6)$$ but glucose has a six member ring and fructose has a five member ring structure. Fructose is known as the fruit sugar as its source in the diet is fruits and vegetables. Honey is also a good source. Glucose is known as grape sugar, blood sugar or corn sugar as these are its richest sources. Sucrose is the sugar we know as sugar or table sugar. Typically extracted as cane or beet sugar. If sucrose is treated with acid or heat, it hydrolyses to form glucose and fructose. This mixture of sucrose, glucose and fructose is also called invert sugar.
