AS.020.305 Chapter Notes - Chapter 1: Thermodynamics, Chemical Polarity, Genetic Code
Document Summary
Biochemistry: the study f the chemistry of life processes: many fundamental processes of living things have been discovered, but there is still much to figure out. The biological world is extremely diverse: the invention of the microscope helped reveal a key unifying feature of all living things: cells. The fact that all living things are made up of cells suggests that all organisms have more in common than was previously expected. The field of biochemistry has helped expand these ideas. Molecule classes: members of these classes are common to all living things. Metabolites: glycerol, glucose, etc: low molecular weight molecules, key metabolic processes are common to many organisms. That all living things share a common ancestor. Eukarya: all multicellular organisms and many unicellular organisms (yeast: defining characteristic: the presence of a well-defined nucleus within each cell. Prokaryotes: unicellular organisms classified into two separate domains: bacteria, archaea. Dna: the biochemical feature common to all organisms.
