Catalysis

which has four binding sites for biotin or biotinylated derivatives with extraordinary affinity. Biotin can be chemically coupled to a binder molecule (e.g., a protein, DNA, hormone, etc.) without disturbing the interaction with its target molecule by a procedure called biotinylation. Avidin can then be exploited to “sandwich” between the biotinylated binder and a targeting molecule or probe. Avidin was also coupled with a functional moiety in some cases. Through the avidin-biotin system, we can…

Dead’s tradition of being a terrible family. Pilate does not reflect this portion of Solomon showing Milkman the truth of what families should be. In a sense, Pilate is a reincarnation of Solomon’s flight and rejection of identity which leads to the catalysis of Milkman doing the same. He rejects the Dead identity to…

The role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…

There are a handful of players you think of when you think of the greatest NBA players ever, whether it be statistically or just the one that captured you, or your parents hearts as kids growing up. Who is really the best? Michael Jordan is absolutely, without a doubt the greatest basketball player ever. What makes Michael the best from the other greats like, Hakeem Olajuwon, Bill Russell, Wilt Chamberlain, and Elgin Baylor? Many things separate him from the others, not just his scoring,…

1.5. Enzyme-Polysaccharide Interactions Proteins and enzymes have become an integral part of many industrial processes as well as being applied both in cosmetics and in therapeutics. Due to advances in biotechnology and genetic engineering, mass production of protein and enzymes has become feasible. Use of enzymes is environmentally friendly as they catalyse reactions under mild conditions against polluting inorganic catalysts which works in the extremes of pH and temperature. However, this can…

How should we think about ethics? In order to answer this ultimate question, we must first understand the crucial concepts of ethics, but before we look into the concepts, it is essential to state the basic definition of ethic because the word “ethics” is the basis of the question. In our society, ethics is commonly defined as the study of morals, which are the standards of right and wrong that show humans what to do. Knowing this, we can continue with the concepts of ethics. First of all, we…

FINANCE AND ACOUNTS DEPRTMENT Each company is carried with a cause of being profitable. Cash or capital being a scare in addition to vital aid in the working of any agency desires to accept prime significance. The financial resources were deliberate and managed in a proper and non-stop manner. As most of the maximum crucial choices of a firm are the ones which relate to finance. Finance & debts from an integral a part of any organisation. proper and clean functioning of this segment could be…

Chitin is the second most abundant natural polysaccharide consisting of β(1→ 4)-linked N-acetyl-D-glucosamine (GlcNAc) units in a linear form. Chitin is insoluble in water and mainly exists in two crystalline (α- and β-) forms. The α-chitin consists of sheets of tightly packed alternating parallel and antiparallel chains (1) and is abundant in the exoskeleton of arthropods, insects, fungi, and yeast cell walls. The chains are arranged in parallel orientation in β-chitin (2), which occurs less…

The Effects of an Enzyme, Catechol Oxidase, on the Conversion of Four Different Substrates to Pr oduce Benzoquinone. Amir Akhras Lab partners: Monica Elabed, Andres Velazquez, and Roland Rencz Biology 201 Instructor: Dr. Kara Nuss October 28, 2014 ABSTRACT Enzymes are catalysts that speed the reaction of substrates to produce products. They achieve this by lowering the energy of activation (EA) but they do not change the nature of the reaction. The objective of this…
