Document Summary

Living things are mosaics of cell of cell types derived from different genetic origins. 4 core macromolecules that make up the composition and function of cell membranes. These are 10 times as many bacterial cells in the human body as our own cells, making up. Some provide essential functions, while some are potentially harmful. Microbiome: populations of microbiotic organisms within the human body. one of the rst microbes to colonize a baby. Staphylococcus haemolyticus: resides harmlessly on skin but can become pathogenic inside the body. Bacteroids thetaiotaomicron: intestinal bacteria which makes enzymes to break down plant materials. nucleic acids: make up dna which encodes for the functional products of cells. proteins: make up the structural elements of the cell and perform metabolic activities. polysaccharides (carbohydrates): structural components and sources of stored energy. A cell must have the ability to separate it"s internal environment from the exterior environment. Cell membranes are made up of lipid macromolecules.
