Microbiology Study Guide Chapters 1-6 Chapter 1 Main Themes of Microbiology Microorganisms Most are not Pathogens Prokaryotic-no nucleus or organelles Very simplistic—like bacteria Eukaryotic-has nucleus and organelles like mitochondria Includes fungus‚ and animals Acellular-not even a complete cell Includes viruses and prions like those that cause Mad Cow disease Six main types of microorganisms Bacterium (prokaryotic) Fungus (eukaryotic) Algae (eukaryotic) Virus (acellular)

Quantitative Analysis Finding the Percentage Composition of Nickel in an Unknown Compound Introduction: This section of lab was about using analytical chemistry and learning how to identify the amount of nickel in an unknown substance. The purpose was to use gravimetric analysis to quantitatively separate and weigh insoluble reaction products as well as utilize the mole method to compute the amount and percentage of nickel in an unknown nickel sample. The chemical reaction that took place involved the

Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance equal to

Define metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose‚ amino acids‚ glycerol and fatty acids are broken down into simpler ones. The energy of catabolic reactions is used to drive the anabolic reactions. Anabolism is also enzyme regulated but requires energy for taking the simpler broken down components

How the unknown heroes of the Civil Rights Movement helped organize the March on Washington December 1962: « Things aren’t moving fast enough‚ Martin. »‚ [Bayard] Rustin sighed‚ stubbing out his cigarette in the ashtray. Martin [Luther King Jr] could almost hear the disappointment in his voice. Rustin would never say it explicitly – he was too respectful and tactful - but Martin could sense it. They have known each other for six years now. Rustin helped organize the Montgomery Bus Boycott that
