Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

Stem Cell Research Adult stem cell research is providing opportunities to treat people with a various diseases and conditions. In 2010‚ a man’s ankle refused to heal so the doctor took bone marrow from the man’s pelvic bone with a needle‚ condensed it to about four teaspoons of rich red liquid‚ and injected that into his ankle. Four months later‚ the ankle was healed! Adult stem cells are found in all tissues of the growing human being and‚ according to latest reports‚ also have the potential

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

From inventions such as the six-hundred-year-old printing press to the Facebook and Twitter of today‚ media-based technology has never wavered in its role of expediting communication and opening doors. Social media is the catalyst that society needs in order to move forward. History is riddled with almost constant rebellion and change. Humans are simply not content with standing still‚ but they alone are incapable of achieving change at the rate and the scale at which is

Therefore‚ this study is to see more about the biological hazards in the health sector. Therefore‚ this study will reveal the types of biological agents that can be harmful to health‚ that the spread of biological danger to the health sector employees

Biological weapons include any organism (such as bacteria‚ viruses‚ or fungi) or toxin found in nature that can be used to kill or injure a person. The history of biological weapons starts back way before many people realize. Biological weapons have quite a few advantages and disadvantages. Biological weapons have been used as agents of terror and will continue to be used as such. Biological weapons are extremely dangerous and shouldn’t be used because they have the potential to wipe out entire

Biologists and sociologists view the concept of human behaviours or characteristics quite differently. Biological explanations would suggest that it is genes‚ instincts‚ or evolutionary advantages that determine human behaviour. These types of explanations suggest human traits are predetermined and are difficult to change. Sociologists argue these are misguided explanations for human behaviour because this sort of definition takes away from the obviously observable variations in behaviour throughout
