Carbohydrates may form larger carbon-based macromolecules by combining with which elements? a.) sodium, potassium, nitrogenb.) nitrogen, sulfur, phosphorusc.) potassium, sodium, sulfurd.) silicon, phosphorus, sodium

The correct answer is: B.) nitrogen, sulfur, phosphorus.

Combining with these elements carbohydrates form carbohydrate derivates (acidic sugars, deoxy sugars, sugar alcohols, glycosylamines). Monosaccharides (basic units of carbohydrates) may undergo various changes to form carbohydrate derivatives (modification of sugar molecules by addition substituents other than hydroxyl group).

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
