Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x‚ 40x‚ and 100x (oil immersion) objective lenses‚ which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

This lab was testing different methods to prevent bean beetles form infesting a chickpea harvest. They wanted to find something that would protect the crop from this invasive creature. To do this they created 3 replicate experiments which contained 25g of seeds each group with a different genotype‚ and 5 newly hatched adult C. maculatus were added to the jar. They continued to check this on a weekly basis‚ at the end of the experiment they found that the results where quite different for each jar

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did
