Which of the following is a function of carbohydrates in living organisms?

Detailed Solution for Test: Nucleic Acids, Lipids, and Carbohydrates - Question 4

Carbohydrates serve as a primary source of energy for living organisms. They are broken down into glucose, which can be utilized for various metabolic processes and energy production.

Test: Nucleic Acids, Lipids, and Carbohydrates - Question 5

Which of the following nucleotides is found only in RNA?

Detailed Solution for Test: Nucleic Acids, Lipids, and Carbohydrates - Question 5

Uracil (U) is a nitrogenous base found in RNA, whereas thymine (T) is found in DNA. Adenine (A), guanine (G), cytosine (C) are common to both RNA and DNA.

Test: Nucleic Acids, Lipids, and Carbohydrates - Question 6

Which of the following is a saturated fatty acid?

Detailed Solution for Test: Nucleic Acids, Lipids, and Carbohydrates - Question 6

Saturated fatty acids have no double bonds between carbon atoms and have the maximum number of hydrogen atoms bonded to the carbon chain. Stearic acid is an example of a saturated fatty acid.

Test: Nucleic Acids, Lipids, and Carbohydrates - Question 7

Which of the following is an example of a disaccharide?

Detailed Solution for Test: Nucleic Acids, Lipids, and Carbohydrates - Question 7
