Catabolism and anabolism of nucleic acids

In this video I will explain the catabolism and anabolism of nucleic acids. The nucleic acids they are polymers made up of nucleotides like DNA or RNA.

Let us first recall the concepts of catabolism and anabolism:

The catabolism It is the part of the metabolic process that consists of the transformation of complex biomolecules into simple molecules and in the adequate storage of the released chemical energy in the form of high-energy bonds in adenosine molecules triphosphate.

The anabolism is the set of metabolism processes that result in the synthesis of components cells from low molecular mass precursors, which is why it is also called biosynthesis.

Nucleic Acid Anabolism: Although the nucleotides, or their molecular components, which come from the hydrolysis of some nucleic acids are generally recycled to synthesize others, sometimes it may be necessary synthesize them. Ribose and deoxyribose are obtained in the pentose pathway. Phosphoric acid is a common component of cells. Nitrogen bases are synthesized by complex reaction sequences that start from the skeletons of various amino acids.

Catabolismnucleic acids: Nucleic acids are only catabolized for their renewal. DNA and RNA are first hydrolyzed by the action of nucleolase enzymes. The nucleotides obtained are broken into pentoses, phosphates and bases to form new nucleic acid molecules. The degradation of the bases can form urea or uric acid that is eliminated.

In the video you will be able to understand better the catabolism and anabolism of nucleic acids. In addition, if you are not sure you can continue practicing with problems of this type you can do the printable exercises with their solutions that I have left you on the web. Good luck in your studies!
