Cell Composition: Metabolites and Macromolecules

This lecture covers the composition of the cytoplasm and cell content, including macromolecules and metabolites. It discusses the structure of prokaryotic cells, the role of ribosomes in protein synthesis, the genome size, and the abundance of proteins in E. coli. Additionally, it explores the intracellular ion concentration, the formation of inclusion bodies, and the production and extraction of polyhydroxyalkanoates. The lecture also delves into the metabolism of sulfur, the role of gas vesicles in aquatic bacteria, and the nitrogen cycle. Various cellular structures such as carboxisomes, chlorosomes, and the prokaryotic cytoskeleton are explained.
