Biomolecules key features
1.Life is composed of lifeless chemical molecules. The complex biomolecules, proteins DNA and RNA polysaccharides and lipids are formed by the monomeric ards, nucleotides, munosaccharides and fatty acids, respectively.
2. The cell is the structural and functional unit of life. The eukaryotic cell consists of well hollalar organelles, enveloped in a plasma membrane. 3. The contains DNA, the repository of genetic information. DNA, in association: seth proteins thatonest forms nucleosomes which, in turn, make up the chromosomes
4. The mochondria are the centres for energy metabolism. They are the principal producers
of ATP which is exported to all parts of the cell to provide energy for cellular work
5. Endoplasmic reticulum (ER) is the network of membrane enclosed spaces that extends throughout the cytoplasm ER studded with ribosomes, the factories of protein bithesis is referred to as rough ER. Golgi apparatus are a cluster of membrane veseles to which the newly synthesized proteins are handed over for further processing and export
6. Lysosomes are the digestive bodies of the cell actively involved in the degradation of cellular compounds Percochomes contain the enzyme catalase that protects the cell from the toxic effects of HD. The cellular ground matrix is referred to as cytosol which, in fact, is composed of a network of protein filaments, the cytoskeleton
7. The eukaryotic cells perform a wide range of complex functions in a well coordinated and integrated fashion Apoptosis is the process of programmed cell death or cell suicide
