we know for certain‚ and that is that all life we’ve studied is carbon based‚ evolved in an environment rich in oxygen‚ nitrogen hydrogen and carbon‚ and uses water as a solvent to facilitate biochemical reactions. Although alternative biochemistries are entirely possible‚ and life that is not biochemical but rather electrical or mineral may also be possible‚ if we open the door to these possibilities this report might never end. For the sake of brevity the information I present here will be based

staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate reduction‚ etc. Biochemical testing is very important

pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane Hypotonic refers to less solute concentrations. These conditions will cause a net influx of water into the cells causing the cells to burst or lyse Hypertonic refers to greater solute concentrations. These conditions will cause a net outflow of water from the cell causing the cells to shrivel Heat – the atoms increase in energy causing vibrations within the protein that disrupt 2‚ 3

Battle of the Sciences: Dental Vs. Biochemical Engineering Deciding what I want to do for the next 60 years of my life is a pretty big step‚ especially at the young age of eighteen. Making this decision involves choosing a school that is well suited for me‚ and picking a field to major in. Fortunately‚ I have half of the process figured out. I have chosen to attend Augustana University this upcoming fall (Go Vikings!)‚ but am still undecided as to what my major will be. I have always been fascinated

their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch into smaller molecules. This enzyme will help break down the bread since it is filled of carbohydrates

Title: Virus Module: Biochemical Processes______ All viruses are pathogens. Some viruses are deadly‚ for example‚ HIV and Ebola virus. Unlike bacteria‚ fungi and protists‚ viruses do not fit into the framework of cellular organization that is the hallmark of organisms. Bacteria‚ fungi and protists are cells but not virus. Viruses have unique structural and functional properties and cannot reproduce unless they are inside the cell. In fact‚ they can neither generate energy nor make proteins

Isolation‚ Morphological‚ and Biochemical Characterization. A high-throughput screening of cartenoid-producing microorganisms resulted in 25 astaxanthin-producing bacterial strains from marine water samples that were collected from the Pacific coast of Japan (unpublished results). Among the isolates‚ a novel‚ highly selective astaxanthin-producing marine bacterium‚ labeled strain (N-5)‚ was isolated based on its ability to produce orange pigment on NA plate after 2 days of cultivation at 30 °C.

Biochemical Pathways of Heavy Metals Poisoning BIO101 (Principles of Biology) 6 July 2012 Abstract The biochemical pathways of heavy metal poisoning are routes by which the metals pass in the body as they impair and destroy normal cellular and organ activity. The most common types of heavy metal poisoning are caused by lead‚ arsenic‚ cadmium and mercury. They are also the most extensively studied at the moment. Lead poisoning occurs mainly by the inhibitory effect that the metal imposes on enzymes
