Biochemistry Essay

664 words - 3 pages Previous Weeks Summary: In the first week of lab, we were told to research Alpha-B-crystallin which is a protein found in the lens. In order to find the mRNA sequence and amino acid sequence of Alpha-B-crystallin, the NCBI protein database was used. Followed by this we utilized the Expasy translation tool to reveal our nucleotide sequence of codons from the mRNA sequence. Our start codon was methionine and our stop codon was lysine. We were

The Effect of Different Concentrations of a Substrate On an Enzyme

816 words - 4 pages are used over and over there may be only a small amount of each enzyme present. In this lab activity, you will study the enzyme catalase and its substrate hydrogen peroxide. Catalase accelerates the breakdown of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2). The chemical equation for this reaction is: 2 H2O2 ----Catalase-------> 2H2O + O2 Catalase is found in both plant and animal tissues

We found that a higher concentration of amylase led to a faster rate of reaction, proving our hypothesis to be correct. In our second experiment, we tested the effect the concentration of substrate would have on enzymatic activity. We hypothesized that the lower concentration of the

Investigating The Effect Of Temperature On The Structure Of An Enzyme

1659 words - 7 pages Investigating The Effect of Temperature on the Structure of an Enzyme Introduction: For my GCSE Biology assessment I will be investigating the enzyme amylase with the substrate starch. This reaction, which I am going to investigate, is called the protein test for starch. Aim: My intention for this observation is to examine how the enzyme catalyses are affected by changes in temperature. Safety

Alkaline Phosphatase

1564 words - 7 pages factors when measuring activity, the maximum velocity (Vmax), and the Michaelis constant,(Km). The Vmax can be defined as the maximum rate at a given enzyme concentration that it can work or rate of product formation when active site is saturated.The Michaelis constant, Km, is a measure of the affinity of the enzyme for the substrate, and has the same units of concentration. The substrate used with alkaline phosphatase for this lab was p

Amylase is used in germinating seeds by helping the seed grow. It gives farmers a chance to create the biggest production of corn with the smallest amount of input. Can we prove that temperature affect enzyme activity? In this lab, we tested to see if the rate of enzyme

In fact, your cells are always making poisonous chemicals. They do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You

The Effects Of Temperature On Enzymes

733 words - 3 pages . The activity of enzymes is affected by temperature. The purpose of this lab was to determine the effect of temperature on the rate of enzyme activity. Since the catalase speeds up the decomposition of hydrogen, the rate of catalase activity was measured indirectly by measuring the change in percentage of oxygen produced over a fixed time period. Because enzymes works best at a temperature 37 degrees Celsius and needs to maintain that

1162 words - 5 pages Cheese Lab Background: Enzymes are proteins that catalyze or control metabolic reaction. Enzymes work by lowering the amount of activation energy needed so the reaction will happen more quickly. The molecules that an enzyme acts upon are called substrates, the substrate solutions used in this lab were milk and water. In this lab, the enzymes are specific for particular substrates. The enzyme (junket tablet) converts these substrates into

Another weakness was the time permitted to complete this lab. If we would have had a three hour long lab period as opposed to a 90 minute one, I could have done more trials and test, using different samples of hydrogen peroxide and enzyme catalase. A third weakness was the accuracy of the graduated
