Sugar, which is a product of the photosynthetic process of green plants can be converted to glucose (a simple carbohydrate). Enormous amount of these glucose molecules can be linked together to form a complex carbohydrate called cellulose, which is a polysaccharide because it is made up of a long chain of glucose molecules. The cellulose is ultimately used to build the cell wall of plants.
Anabolism is the production of a complex molecule by a living organism from a much simpler one. Since, cellulose is produced by the building up of glucose molecules, the process can therefore, said to be anabolic
The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
