Document Summary
Nucleus: location of main genome, site of most dna and rna synthesis. Mitochondrion: site of energy yielding oxidation reactions, has its own dna. Chloroplast: site of photosynthesis in green plants and algae, has its own dna. Endoplasmic reticulum: continuous membrane throughout cell, site of protein synthesis. Golgi apparatus: involved in secretion of proteins. Lysosomes: membrane bound sacs containing hydrolytic enzymes. Peroxisome: sacs containing enzymes involved in metabolism of hydrogen peroxide. Monera: only prokaryotic organisms, like bacteria and cyanobacteria. Amino acids are the building blocks of proteins. Comes from the greek word proteios, meaning primary. Aa are composed of an amino group (nh2), carboxyl group (cooh) a hydrogen atom and a distinctive side chain group (r), all attached to a carbon atoms called the alpha carbon from the organic chemistry nomenclature. Only proline, a cyclic amino acid, is the exception, it is called an imino acid but still commonly referred to as an alpha-amino acid.
