Labset Four Worksheet 1. Define the term “selectively toxic.” Why is it an important feature of antimicrobial agents? A substance or drug is selectively toxic if the agent used in it is able to kill the microorganism that it is meant to without harm to the host that has taken the drug. This is very important to microbial agents in that it enables these agents to inhibit a microorganism by interacting with microbial functions or structures different from those of the host; thereby showing little

Systems Biology Systems biology involves the study of an organism as one single system. Instead of analysing all the individual components that make up a cell‚ the cell is instead viewed as an interacting network of genes‚ proteins and biochemical reactions and these are studied as a whole. In 20th century‚ molecular biology was focused upon. A ‘reductionist’ approach was followed‚ in which the individual components‚ such as the cell nucleus or sugar metabolism‚ were studied in isolation. However

What is Food Microbiology Food microbiology is the study of food micro-organisms; how we can identify and culture them‚ how they live‚ how some infect and cause disease and how we can make use of their activities. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point‚ hundreds

Introduction The purpose of this paper was to inform the reader of the importance of microbiology in the world today. Microbiology studies the behavior of microorganisms and teaches students about the effect of bacteria‚ fungi‚ viruses‚ algae‚ and yeast on living things. Studying these microorganisms gives insight to the spread of different diseases and how they

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
