function of the enzymes (enzyme names end in “-ase”) as part of the labels for the diagram(s) and that you labeled the following: • DNA • replication fork • helicase • single-stranded binding proteins • leading strand • lagging strand • 5’ and 3’ ends of all DNA • primase • RNA primer • DNA polymerase III • Okazaki fragments (Borges, 2014) B. Insert your original diagram, or series of diagrams, with clear labels, that show the role of the ligase enzyme in the replication

What is the function of enzymes in a living system? Enzymes speed up metabolic reactions necessary for life. Without them certain vital processes would not take place and the body would be unable to function. Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments? In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example

Ali Ahmad BIO 2710 Wed 12:30PM – 3:30PM Unknown 6: Micrococcus Luteus Introduction: This lab requires us to learn about cultural, morphological and biochemical characteristics that are used in identifying bacteria. These characteristics and unique aspects can be observed by learning and using the various different tests and techniques, which is the main purpose here, and can help pinpoint the identity of the unknown organism. Each student will receive a slant containing one species

Notes Enzymes: What must occur for a reaction to proceed? Collision Theory: 1. Reactants must collide 2. Reactants must have enough energy 3. Reactants must hit with proper orientation Here is morbid example of collision theory. How do a train and school bus react to give a train with engine damage and a school bus in two pieces? [pic] If you look back to the three conditions required for a reaction to occur, we can relate them to his terrible accident. In the collision theory, condition

Enzyme Regulatory Function Enzymes operate as catalysts by increasing and regulating all chemical reactions in a living organism within half the fraction of energy if they were not utilized. What makes enzymes so efficient and unique is that they can increase the rate of a reaction and alter chemical activity at the cellular level while still maintaining homeostasis and cellular equilibrium. In the absence of enzymes it would dramatically alter chemical reactions by decreasing the rate at which

Alzheimer’s disease is slow-fatal disease of the brain, affecting 1 in ten people at the age of 65. No one is immune. The disease comes on gradually as two abnormal protein fragments called plaques and tangles accumulates in the brain and kill brain cells. They start in the hippocampus. Where memory where first formed .over many years time plaques and tangles slowly destroy the hippocampus and it becomes harder and harder to form new memories. Simple recollection from a few hours or days ago but

Introduction & Hypothesis: Enzymes are important for every living organism, because they are the reason that reactions occur. Although most reactions would take place without enzymes, enzymes allow these chemical reactions to happen at a much faster rate, therefore making cells more efficient (Reece, 2011). Enzymes are catalysts, and almost always proteins, that speed up the rates of reactions by lowering the activation energy without being consumed in the reaction (Helms, 1998). Throughout this

Aseptic packaging or processing is where a food product, such as ultra-high temperature (UHT) milk) and its package is sterilized separately and then combined and sealed under sterilized atmosphere. The first practice of this was in Denmark in 1913 packing milk in metal cans. In 1921 a patent was granted for the process under the term aseptic conservation. In 1923 aseptically packaged milk from South Africa was shipped to London to a trade fair and it arrived in perfect condition. In 1933 a filling

1. Introduction: Chitosan is a natural biodegradable polymer composed of 2-amino-2-deoxy-β-D-glucose (D-glucosamine) with β (1-4) linkage, and with occasional N-acetyl glucosamine residues (Austin et al., 1981). This is a biopolymer that is consistently playing an important role in the world’s economy since it is biocompatible, biodegradable, edible, and antimicrobial (Muzzarelli & Muzzarelli, 2005). As compared with other bio-based food packaging materials, chitosan has antibacterial activity by

Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. Most of them are proteins. They speed up metabolic reactions in the body but remain chemically unchanged themselves In the experiment, the enzyme amylase was involved.this enzyme takes part in the digestion ofcarbohydrate. digestion is the break down of large complex and insoluble food into small simple soluble molecules for the body to absorb it. starch is a complex, the body have
