| Question | Answer |
|---|---|
| Adenosine triphosphate (ATP) | ATP is a molecule that can pick up energy and give it to another chemical process; therefore it is often called the energy currency of cells. |
| Ribonucleotides - RNA | contain the sugar ribose instead of deoxyribose and the nitrogenous base uracil instead of thymine |
| deoxyribonucleotide DNA | Consist of pentose sugar named, deoxyribose |
| NUCLEIC ACIDS AND RELATED MOLECULES (DNA AND RNA) | Survival of humans as a species—and survival of every other species—depends largely on two kinds of nucleic acid molecules. |
| Quaternary Protein Structure | A quaternary structure protein is one that contains clusters of more than one polypeptide chain, all linked together into one giant molecule. |
| peptide bond | is one that binds the carboxyl group of one amino acid to the amino group of another amino acid. |
| Structural proteins | form the structure of the cells, tissues, and organs of the body. Various unique shapes and compositions such as flexible strands, elastic strands, and waterproof layers allow structural proteins to form the many different building blocks of the body. |
| Prostaglandins | often called tissue hormones, are lipids composed of a 20-carbon unsaturated fatty acid that contains a 5-carbon ring. |
| polyunsaturated fatty acids | have more than one double bond. |
| Glycogen | a polymer of glucose, is sometimes referred to as animal starch. It is the main polysaccharide in the body and has an estimated mo-lecular weight of several million—truly a macromolecule. |
| carbon atoms | have only four electrons in their outer energy level, four additional electrons are required to satisfy the octet rule |
