Concept explainers

Nucleotides

It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Nucleic Acids

Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

If you are using cellular respiration to get energy from proteins rather than carbohydrates, which of the following is true? there are completely different reactions for protein breakdown as compared to carbohydrates so a different set of pathways is used the amino acids must be broken down into individual C-H or C-C bonds and then those bonds will join with others to create a sugar that enters into the glycolysis pathway O the amino acids are joined with a covalent bond to a sugar and then the hybrid molecule will enter the cellular respiration pathways the amino group is removed and then the rest of the molecule is converted into molecules such as pyruvate or oxaloacetate that can then enter cellular respiration pathways O the amino acids must first be converted into glucose and then they can go through the cellular respiration pathways
