Question

Which carbohydrates are found in our genetic material?

A. fructose and galactose
B. sucrose and fructose
C. deoxyribose and ribose


Question 5.5. The process of linking monosacchrides to become polysaccharides is called _________, while breaking down polysacchrides, like glycogen, occurs during a process called _________.
A. hydrolysis; dehydration synthesis
B. dehydration synthesis; hydrolysis
C. hydrolysis; polysynthesis

Answer 1

Deoxyribose and ribose are found in our genetic material.
The process of linking monosacchrides to become polysaccharides is called dehydration synthesis, while breaking down polysaccharides, like glycogen, occurs during a process called hydrolysis.

Answer 2

1. The right answer is C. deoxyribose and ribose.

Ribose is a pentose of the D series, all hydroxyls of which are oriented to the right (Fisher's representation). In ribonucleic acids (RNA), it is cyclized to ribofuranose: β-anomer specifically.

Deoxyribose, a component of deoxyribonucleic acids (DNA), is derived from ribose by a reduction of the secondary alcohol function of carbon # 2. Deoxyribose confers on this nucleic acid a greater stability peculiar to its function of conserving genetic information.

2. The right answer is B. dehydration synthesis; hydrolysis.

Dehydration synthesis takes place during the synthesis of molecules, a chemical dehydration reaction during which a molecule of water is released; it is also called condensation reaction or dehydration reaction. A peptide bond, or a glycosidic moiety, may result from dehydration synthesis.

Hydrolysis is any chemical reaction in which there is a breakage of a molecule by water. We will have a decomposition of a body by fixing the H + and OH- ions coming from the dissociation of the water. Hydrolysis reactions play an important role in biochemistry.
