Exploring the Properties and Functions of Enzymes

Exploring the properties and functions of enzymes Introduction In this experiment, we examine the effect of temperature change on catalytic reaction and optimum temperature. Main factors (variables) How to control the temperature of hydrogen peroxide H202 If the temperature of hydrogen peroxide is higher or lower than the correct temperature, control this variable as the test is not fair. Results may be affected. Influence of temperature

Section 1: Introduction Enzymes are proteins used to promote biochemical reactions. Enzymes can only react with so-called substrates. This is because the enzyme has a unique shape that allows specific action properties, such as complete matching of the matrix. This substrate fixes itself to the enzyme and produces the product. Lactase is an enzyme that degrades lactose, and lactose is lactose of galactose and glucose. - In the human body, cells can reveal abundant genetic information leading to diagnosis and answers to specific clinical symptoms. DNA is a part of a cell and is a nucleic acid containing a molecule that stores important information. Human DNA is unique to them, it determines the appearance of a person, the color of hair and eyes. DNA also contains genes and is involved in the chromosome Cells need to replicate DNA in order to breed.

In the 1950s and 1960s, DNA was found to be essential for protein synthesis. In many functions, proteins can function as enzymes and structural materials in cells. Many specialized proteins are involved in cellular activities, for example in humans insulin of hormones and filaments of myocytes are composed of proteins. Human hair, skin, nails are made of protein. There are thousands of enzymes in the body as well. The key to protein molecules is how amino acids are related. The amino acid sequence within a protein is a code that identifies a protein and distinguishes it from a protein. This amino acid code is determined by the genetic code of DNA. The genetic code consists of a nitrogen-containing base sequence in DNA. How nitrogen-containing base codes are translated into protein amino acid sequences is the basis of protein synthesis

This enzyme is usually a globular protein that acts alone or in larger complexes. The sequence of amino acids specifies the structure, which in turn determines the catalytic activity of the enzyme. The structure determines function, but individual structures do not predict new enzyme activity. When heated or exposed to chemical denaturants, the structure of the enzyme develops (degenerate), and this damage to the structure usually results in a loss of activity. Enzyme denaturation is usually associated with temperatures above that normal level; therefore, enzymes living in volcanic environments such as hot springs are preferred by industrial users due to their function at elevated temperatures, and enzymatic catalysis At a very high speed.
