Carbohydrates may form larger carbon-based macromolecules by combining with which elements? a. sodium, potassium, nitrogen b. nitrogen, sulfur, phosphorus c. potassium, sodium, sulfur d. silicon, phosphorus, sodium

Answer;

B.nitrogen, sulfur, phosphorus

Explanation;

-Single units of carbohydrates called monosaccharides may undergo various reactions to form carbohydrate derivatives. Derivatives in case of carbohydrates often means modification of sugar molecules by addition substituents other than hydroxyl group.

-Amino sugars, acidic sugars, deoxy sugars, sugar alcohols, glycosylamines, and sugar phosphates are examples of carbohydrate derivatives.

-After combining with elements, a transformed molecule of sugar resembles structure of a sugar and an added substituent; however, it is not considered as sugar anymore because its function and characteristics has changed.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
