by my family to study hard. I did not know what they truly meant until I was in grade twelve. I realized that studying hard will help to have good grades. Having good grades will lead me to attending a university. I was very stressed in my last year of high school because I wanted to prove to my family that I am smarter than what they believed. I did not receive honor roll when I was in grade nine‚ ten or eleven. Grade twelve was the year where I finally knew how to study. Funny‚ right? Throughout

was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise

Enzyme Specificity Using Beta-galactosidase and Alpha-galactosidase Introduction: In order to survive‚ organisms need reactions to occur at a certain time and place. Enzymes make these reactions happen. Enzymes are highly specific causing only one enzyme to catalyze one reaction. “Induced fit” explains why enzymes act this certain way. An enzyme will surround a certain substrate and form to it for the reaction to occur in the active site. If it doesn’t form to it‚ the reaction will not occur

To facilitate the metabolic rate of the cells in the body trace elements‚ existing in the form of ions and cations‚ act as the cofactors in useful enzymatic chemical reactions in the cell body.
