2.Carbon is an integral part of many biological processes, including reproduction, photosynthesis and respiration.

3.carbohydrates, lipids, proteins, and nucleic acids

4.Most macromolecules are made from single subunits, or building blocks, called monomers.

5.by a specific enzyme

6.primary role of carbohydrates is to supply energy to all cells in the body

7.The main difference between Monosaccharides Disaccharides and Polysaccharides is that monosaccharides are monomers of sugars and disaccharides are composed of two monomers whereas polysaccharides are composed of a large number of monomers.

8.Polysaccharides are long chains of monosaccharides linked by glycosidic bonds.Starch and glycogen serve as short-term energy stores in plants and animals, respectively.

9.polysaccharides are large high-molecular weight molecules constructed by joining monosaccharide units together by glycosidic bonds.

10.fats and oils, waxes, phospholipids, and steroids

11.macromolecules are made from single subunits, or building blocks, called monomers.
