Question

Starch, glucose, galactose, and cellulose are the examples of:

• A. Lipids
• B. Vitamins
• C. Proteins
• D. Carbohydrates

Answer 1

The correct option is D

Carbohydrates

Explanation for the correct option:
(D) Carbohydrates

• Starch, glucose, galactose, and cellulose are examples of carbohydrates.
• A large group of organic compounds occurs in foods and living tissues and including sugars, starch, and cellulose.
• They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.

Explanation for the incorrect options:

(A) Lipids

• Lipids are an essential component of the cell membrane.
• The structure is typically made of a Glycerol backbone, 2 fatty acid tails, and a Phosphate group.

(B) Vitamins

• Vitamins are organic compounds that are required by advanced animals in small amounts on a regular basis.
• Like essential amino acids, there are 13 vitamins that are required but not produced by the human system.
• Unlike essential amino acids, these vitamins are required in minute quantities.

(C) Proteins

• Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains.

Hence, option (D) is correct. Starch, glucose, galactose, and cellulose are examples of carbohydrates.
