Enzymes Essay

569 words - 3 pages POLYMERASE OR REPLICASE ENZYMES: A polymerase enzyme catalyses the formation of a polymer and cellular polymerase enzymes of genetic interest are those that bring about the synthesis of one polynucleotide chain that is copy of another. A polymerase enzyme is called replicase enzyme when the copy of the polynucleotide chain so produced is inherited by daughter cells or viruses, that is, when the enzyme brings about chromosomal replication. PROKARYOTIC DNA POLYMERASES: Three different DNA polymerases are known in E.Coli and other prokaryotes, of which DNA polymerase I and II are meant for DNA repair and DNA polymerase III is meant for actual DNA replication. 1.

Enzymes would temporarily bond to one or more reactants of a reaction and catalyze, meaning they speed up the process with lower activation energy needed. Enzymes provide a variety of functions such as cells using an enzyme to rid themselves of a poisonous substance (hydrogen peroxide) and also energy usage. catalase 2H2O(l) ( 2H2O(l) + O2(g) This lab measured the time it took for a disc of filter paper soaked with different concentrations of enzyme to make its way to the surface of the test tube containing peroxide.

Transcription Essay

315 words - 2 pages molecules attach to and the amino acids they carry are linked to form a polypeptide, this is translation. Transcription is the process of making pre-mRNA using part of the DNA as a template. The enzyme DNA helicase acts on a specific region of the DNA molecule to break the hydrogen bonds between the bases, causing the two strands to seperate and expose the nucleotide bases in that region. This causes the specific region called cistron to unwind. One of the strands is used as a template to make an mRNA copy.The enzyme RNA polymerase moves along one of the two DNA strands, known as the template strand causing the nucleotides on this strand to join with the individual complementary nucleotides VIEW DOCUMENT

8305 words - 34 pages , vitamins do not provide any energy to the body. (Rolfes, Pinna, Whitney 322) Vitamins are also individual units, not complex chains of molecules. Vitamins also vary from energy yielding nutrients in the way that they are measured. Vitamins are usually measured in micrograms (µg) or milligrams (mg), while energy yielding nutrients are usually measured in grams (g). There are two distinct similarities between the two. This is that both vitamins and energy-yielding nutrients are available from foods, and they are extremely important in supporting life.

This effect had been demonstrated in burn injuries; in particular, partial-thickness burns wounds were “prevented from developing to full-thickness burn wounds by application of honey dressings” (Sharp, 2009, p. 70). Furthermore, honey increases the activity of the enzyme plasmin, which effectively digests fibrin that attaches slough to the wound surface without digesting collagen matrix needed for tissue repair. A study found that the increased plasmin activity is a result of honey inhibiting the production of plasminogen activator inhibitor (PAI), an enzyme that would have otherwise block the enzymatic VIEW DOCUMENT
