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

is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants‚ photosynthesis can be said to be the source of our life also. As the chlorophyll in leaves decays in the autumn‚ the green color fades and is replaced by the oranges and reds of carotenoids. Xanthophyll is the yellow pigment in plants that‚ like chlorophyll‚ is responsible for the production of carbohydrates by photosynthesis. Chromatography

proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate that responds with an enzyme is used to view

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are
