and there are numerous amounts. Many enzymes are essential for life and reactions would not happen rapidly to maintain life with the help of enzymes. Specific enzymes lower the activation energy for specific reactions and shapes. Activation energy is required to start a chemical reaction. This occurs when energy is added to reactants. Amino acid chains are made up by their unique folds which results in formation. Since enzymes are proteins‚ each one consists of its own amino acid in a specific order

Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space

William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

Fossil Fuels America’s Dependency on Fossil Fuels America’s Dependency on Fossil Fuels For the past two hundred years the United States depends more on fossil fuels than any other power source. Without fossil fuels‚ the industrial revolution would not have had as much of an impact making United States what it is today. However‚ we as a country are facing very real problems that we must have to address quickly. We are running out of fossil fuels‚ and soon we will not have fossil fuels to power

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

fields use S.Cerevisiae) as a model organism” (Simpson‚2010). Fermentation is the metabolic procedure in which an organism alters a carbohydrate‚ such as sugar or starch‚ into an acid or alcohol. For instance ‚ yeast performs fermentation to achieve energy by altering sugar into alcohol. Bacteria execute fermentation‚ altering carbohydrates into lactic acid (Helmenstine‚ 2013). Fermentation can be used in the food and drink industry as well‚ examples of this is bread. In the process of fermentation

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms
