1. Repair of tissue means cell division. This implies nucleic acids which have the instructions to produce new cells. 2. Carbohydrates such as glucose provide energy for life functions. 3. Amino acids are the building blocks of proteins.  4. A concentrated, stored energy source is lipids, an example is fat.  5. Simple carbohydrates are monosaccharides, a type of sugar. 6. Nucleic acid contain information on how to build proteins. 7. Starch and cellulose are complex carbohydrates. 8. Steroids and some vitamins are in the lipid category of organic compounds. 9. RNA and DNA are two nucleic acids found within cells. 10. Extra sugars are joined by dehydration synthesis to form starch, a complex carbohydrate. 11. Butter, oil and wax are examples of lipids. 12. DNA is the nucleic acid that never leaves the nucleus. 13. When new tissue is built, ribosomes manufacture proteins. However, the instructions of nucleic acids are needed to direct this process of translation.
