HCl increases the acidity of the stomach to about pH2 – the optimum pH for stomach enzymes. oesophagus duodenum mucus cells parietal cells (acid-producing) gastric gland. 15.
O.P. Ward, in Comprehensive Biotechnology (Second Edition), 2011 Abstract. Proteases are ubiquitous in biosystems where they have diverse roles in the biochemical, physiological, and regulatory aspects of cells and organisms. Proteases represent the largest segment of the industrial enzyme market where they are used in detergents, in food processing, in leather …
Nov 30, 2009·Extraction of DNA, RNA, and protein is the basic method used in molecular biology. These biomolecules can be isolated from any biological material for subsequent downstream processes, analytical, or preparative purposes. In the past, the process of extraction and purification of nucleic acids used to be complicated, time-consuming, labor-intensive, and …
Oct 10, 2021·The basic criteria that any method of DNA isolation from any sample type should meet include: (1) efficient extraction of DNA from the sample , (2) production of a sufficient amount of DNA for use in downstream processes, (3) successful removal of contaminants, (4) isolation of high quality and high purity DNA.
Life Sciences Grade 10 www.learnxtrao Brought to you by Page 3 Overuse of fertilisers causes large amounts of nitrates and phosphates to be leached out of the soil into rivers, dams, and lakes Excess nutrients stimulate the growth of aquatic plants and algae Decomposition of the plants and algae uses large amounts of oxygen and prevent oxygen from penetrating deeper
Immunohistochemistry (IHC) is a method for detecting antigens or haptens in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues. The antibody-antigen binding can be visualized in different manners. Enzymes, such as Horseradish Peroxidase (HRP) or Alkaline Phosphatase (AP ...
Bioremediation is any process that uses decomposers and green plants, or their enzymes, to improve the condition of contaminated environments.Bacteria can be used to clean up oil spills in the ocean through bioremediation. Specific bacteria can be used to bioremediate specific contaminants, such as hydrocarbons, which are present in oil and gasoline.

A biological washing powder contains enzymes. This is commonly used in the United Kingdom because other washing detergents are called "non-biological". Some people can be allergic to enzymes.
It is commonly one of the first steps in a purification scheme. • Purification procedures attempt to maintain the protein in native form. Although some proteins can be re-natured, most cannot! • To purify a protein from a mixture, biochemists exploit the …

The leaf consist of a broad, flat part called the lamina, which is joined to the rest of the plant by a leaf stalk or petiole. Running through the petiole are vascular bundles, which then form the veins in the leaf. Although a leaf looks thin, its is made up of several layers of cells.
Enzyme. =. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.
