Essays on Enzyme

Enzymes What Are Enzymes? Substances that speed up chemical reactions are called catalysts. Organic catalysts are called enzymes. Enzymes are specific for one particular reaction or group of related reactions. Many reactions cannot occur without the correct enzyme present. They are often named by adding “ase” to the name of the substrate. Example: Dehydrogenases are…

Restriction enzymes (also known as restriction endonucleases) are a group of bacterial enzymes which cut double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses, thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA…

An enzyme is a catalyst, which is a chemical agent that changes the rate of a reaction without being consumed by the reaction. The reactant that an enzyme acts on is called its substrate. While the enzyme is bound to the substrate, the catalytic action converts the substrate to the product. Because of its shape,…

The Current Structural and Functional Understanding of APOBEC Deaminases (Running Title: Structural Insights for APOBEC Deaminase) Keywords: APOBEC, cytidine deaminase, Viral Infectivity Factor (Vif), Human Immunodeficiency Virus (HIV), DNA deamination, RNA editing Abstract: The Apolipoprotein B mRNA-editing Enzyme Catalytic polypeptide family of cytidine deaminases has emerged as an intensively studied field as a result of…

Resources in Indonesia are very large, especially sources that are food. One of the abundant resources in Indonesia is its fisheries resources, therefore the food must be processed in such a way as to have good quality and quality. Good quality and quality can help increase economic value and nutritional value in the community. There…

The oxygen can be observed as bubbles comic Eng from the reaction site. Catalane is found in many living tissues of organisms, including chicken liver. T he purpose of this experiment is to determine what changes in pH, temperature, and enzyme co concentration have on the rate catalane works to break down hydrogen peroxide. If…

How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case, H2O2 will produce more O2, in return the kpa/min will go up. What do you think will happen to the rate of reaction if the concentration of…

How has this been formed from the Deoxyribonucleic acid strand? The enzyme RNA polymerase has synthesised this RNA fragment from a template strand of DNA. Transcription factors inserted RNA polymerise between the strands of DNA, which so uncoiled and unzipped a little part of the dual spiral. Traveling the length of the written text unit,…

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However, different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times. (3) In our human body, there are a total about forty thousand types of enzymes…

The enzyme amylase will catalyze the hydrolysis of starch to maltose when the pH is near 7.0. But when the HCl is added to the solution the amylase will be denatured which results in the enzyme being deactivated. The iodine serves as an indicator for the presence of starch. Iodine (I2) will reach with iodide…
