Electron Microscopy Electron microscopy is used to examine specimens which require greater detail than can be seen when using the light microscope. In comparison to light microscopes electron microscopes provide a clearer picture‚ greater magnification and greater resolution. There are two types of electron microscope; the scanning electron microscope and the transmission electron microscope. Electron microscopes use electromagnetic and electrostatic lenses and some are able to magnify the specimen

explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

Chapter 5 – Short answer a) Phosphorylation - the addition of phosphate to a chemical compound b) What are the 3 mechanisms of phosphorylation used by organisms? • Substrate level phosphorylation – ATP is generated when a high-energy phosphate is directly transferred from a phosphorylated compound (substrate) to ADP • Oxidative phosphorylation – electrons are transferred from a group of organic compounds to a group of electron carriers (NAD+ and FAD); occurs in inner mitochondrial

Microbiology is a field of science which typically is divided into several areas such as: bacteriology‚ virology‚ parasitology and immunology. The goal of microbiology is to increase the specific knowledge of a known microorganism and by extension counter the spread of harmful microorganisms and to learn practical applications of research results. A microbiologist studies the structure‚ metabolism‚ genetics and ecology of microorganisms such as bacteria‚ viruses‚ fungi or algae. A microbiologist
