Document Summary
Cells and microbes can be viewed as (unifying theme: biochemical catalysts. Maintaining a thermodynamic energy flow far from equilibrium defines life. Enzymes: supply energy, precursors for biosynthesis, catalytic machinery: genetic coding devices. Ability to do this needs to be kept and transferred. Replicating dna and forming rna and proteins (transcription, translation) Microorganisms: a microscopic organism consisting of a single cell, cell cluster or virus that carry out processes independently of other cells. Other life is dependent on these organisms influence medicine, agriculture and industry. ~table 1. 1 (distribution of microorganisms in and on earth)~ Electron microscope: 1nm 100um light microscope: 0. 1um 1mm. What people used to believe: unseen forces responsible for disease, seeing is believing, predominant theory was spontaneous generation, took about 200 years to over come theories. Built microscope 30x, began mapping out veins on leaves: molds/fungi = 10um. Cell theory: small compartments of life , revolutionized how people saw things. Able to see things 10-50 times smaller than hooke.
