Document Summary
All cells are bound by a plasma membrane; have a cytosol with metabolites, coenzymes, inorganic ions, enzymes; have a set of genes contained within the nucleoid (prokaryotes) or nucleus (eukaryotes) Bacterial cells have a cytosol, nucleoid, and plasmids. Eukaryotic cells have a nucleus, multiple compartments, certain processes in specific and separate organelles. 4 major classes of biomolecules: proteins, lipids, nucleic acids, and polysaccharides. Biomolecules are polymers of simple building blocks the final product is more complex than its individual components. Carbon has a bonding versatility: chiral carbons. Molecular configuration is only changed by breaking bonds. Conformation is the rotation of atoms within a plane around single bonds. Living cells are open systems: they exchange matter and energy with their surroundings, maintain selves in dynamic and steady state, harvest energy from sunlight, fuels, elections. Chemical reactions have the tendency to go towards equilibrium = g (change in free energy)
