How Enzymes work in the home and in industry essay
This essay aims to explore the ways on how enzymes are used in home and in industry, and it aims to explain the advantages and disadvantages of using enzymes in the home and industry. An enzyme is a protein that is formed by the body that acts as a catalyst to cause a certain desired reaction. Enzymes are very specific. Each enzyme is designed to initiate a specific response with a specific result.

Firstly, the AQA Science Biology textbook published in 2011 by Nelson Thornes Ltd suggests on page 172 that “in the past, people boiled and scrubbed their clothes to get them clean – by hand! Now we have washing machines and enzymes ready and waiting to digest the stains.” This is telling us how people now use enzymes at home and it is much easier from the past. This is an example of how enzymes are used in homes. Enzymes are used to get rid of the stains that are on the clothes in washing machines.

Enzymes are used to break down proteins and fats that are in the stains. This is evident in the same textbook on the same page number mentioned above when it says, “many people use biological detergents to remove stains such as grass, sweat and food from their clothes. Biological washing powders contain proteases and lipases.” Proteases and lipases are those enzymes that are used to break down the proteins and fats that are in the stains. In addition, it is better to use biological detergents instead of non-biological detergents at lower temperatures because that is when the enzymes work at their best, if the water is too hot then they are denatured and this also means that you use less electricity.

The edited book version called ‘Enzymes in Industry’ written by Dr Wolfgang Aehle published in 2007 suggests that “in the food industry enzymes are used to improve dairy products like cheese or to supply us with breads that have the right crumb structure and give us the right mouth feel while eating.” This is...
