Introduction: Enzymes are a substance produced by a living organism that acts as a catalyst to activate a specific reaction. The purpose of this experiment was to figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that

Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering the products of the reaction and without

Gender roles is a set of societal norms which dictate the types of behaviors which are generally considered acceptable‚ appropriate‚ or desirable for people based on their actual or perceived sex. Gender roles have positive and negative impacts on male and female roles. There are traditional gender roles that are influenced by biological‚ social and cultural factors. One way gender roles can be influenced are by biological factors. Biological factors are the process when XX and XY chromosome develop

GROUP 6 ANIMAL CELL and It’s Functions ANIMAL CELL: About animal cell usually have an irregular shape. are eukaryote cells‚ or cells with a membrane bound nucleus. DNA is housed within the nucleus. Also contain other membrane bound organelles‚ or tiny cellular structures that carry out specific functions necessary for normal cellular operation. smaller than plant cells. Cell Membrane is the outermost component of a cell. it is composed of 55% proteins‚ 25% phospholipids

Restriction Enzymes Restriction enzymes (also known as restriction endonucleases) are a group of bacterial enzymes which cut double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses‚ thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA into smaller fragments (called restriction fragments) and the highly specific way in which they do this

Biological and Psychological Models of Abnormality Introduction The many different models used to explain the nature and treatment of mental illness compound the problems of defining and classifying abnormal behaviour. Five major schools of thought are summarised below. The biological (medical) model The medical of abnormality model has dominated the psychiatric profession since the last century . The underlying assumption of this model is that mental illnesses resemble physical

of the population and the steady progress in the field of biological sciences‚ treatment of diseases and protection against pathogens have become more complex than ever. Technology sheds light on how to treat diseases‚ thus different quantitative experimental techniques and mathematical analyses for improving biological research are available‚ yet healthcare costs are skyrocketing‚ and the knowledge on how macromolecules work and how cells regulate gene expression has been a quandary.

Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment
