Describe the Use of Biological Washing Powders That Contain Enzymes

3 Enzymes extracted from bacteria are used in biological washing powders. Investigate and describe the use of biological washing powders that contain enzymes Extended.

2

Washing powder has a history of more than 100 years.

. Stains on clothes are organic molecules biological washing powders contain enzymes similar to digestive enzymes the enzymes help breakdown larger molecules easily insoluble molecules will turn into soluble ones. 4 -both denatured by high temperatures. 24 Use of enzyme in biological washing powders Biological washing powders contain protease and lipase to remove protein stains and fat grease from clothes.

Picture 810 A biological washing powder. A Complete Table 21 by naming the enzymes that break down three substances in food stains and by stating the product or products. Figure 2 a Many of the substances causing the food stains are large insoluble proteins.

They are affective at lower temperatures. The enzyme may be a protease to break down protein stains or a lipase to break down fats and oils lipids. Biological means the washing powder formula uses enzymes as a way of achieving a really deep down clean.

Name two other uses for enzymes in the home. The graph shows the effect of temperature on a protease that could be used in washing powder. Respiration digestion is called.

Use 6 a Define the term enzyme. Pectinase is used to extract fruit juice by breaking down the pectin in the cell walls in fruits. Washing Powder with Biological Enzymes Works Better for Cleaning.

A Complete Table 21 by naming the enzymes that break down three substances in food stains and by stating the product or products. This reduces fuel costs. 2 b Enzymes are used in biological washing powders.

B Describe how bacteria are used to produce enzymes for biological washing powders. Amylases break down starches and lipases break down fats and grease. Explain enzyme action with reference to the active site enzyme-substrate complex substrate and product Explain the specificity of enzymes in terms of the complementary shape and fit of the active site with the substrate.

One of the primary reasons that enzymes are used in biological washing powders is that the additional stain-removing help from the enzymes means that dirt can be removed without the need for hot water. The process where an enzyme is fixed to an inert material by chemical or physical means eg. The breakdown of protein and fat molecules is called hydrolysis.

This reduces fuel costs. How does catalysis work in a washing powder. Biological washing powders contain enzymes which.

Describe the use of biological washing powders that contain enzymes. Blood contain the red protein Haemoglobin Hb. Investigate and describe the use of biological washing powders that contain enzymes Extended Investigate and explain the use of lactase to produce lactose-free milk Describe the role of the fungus Penicillium in the production of the antibiotic penicillin Explain how fermenters are used in the production of penicillin.

A type of chemical reaction which breaks down a large molecule into simpler ones using enzymes eg. 31 describe the effect of increasing temperature on the activity of the enzyme. Washing powders often contain enzymes from bacteria.

These enzymes include proteases that hydrolyse proteins in clothing stains. Washing powder is an alkaline synthetic detergent. Figure 2 shows his results.

Parveensaidask Enzymes in washing powders. Biological detergents are effective at much lower temperatures helping families all across the UK to save money on their household bills and become more. Proteases break down proteins so are good for blood egg gravy and other protein stains.

2 Biological washing powders contain enzymes that break down food stains. German Henkel invented washing powder for the first time in 1907 using borate and silicate as the main raw materials. Because stains are made of different types of molecules a range ofenzymes are needed to break them down.

This almost certainly means that you can wash at lower temperatures and with less water to achieve a really deep down clean. Hope this will help u. Table 21 substance enzyme products starch fat protein 3 Some students compared how effective biological and non-biological washing powders are at.

Substance enzyme products starch fat protein 3 Some students compared how effective biological and non-biological washing powders are at. Biological washing powders contain protein- fat- and carbohydrate-digesting enzymes to help remove stains. 3 ii Explain why the temperature.

Different enzymes are suitable for different applications and fabrics. 31 Using the information in Fig. Explain the shape of the curves at 50 C and 60 C.

Catabolism OR Catabolic reaction. Summary Biological washing powders contain enzymes used to break down stains at low wash temperatures. Enzymes lipase in biological washing powders are used to break down fats or grease on clothes and protease used to break down proteins such as blood stains.

Investigating enzymes used in laundry detergents- the use of enzymes in biological washing powders 1 A suitable dilution of detergent is around 5 that is 5 cm 3 of detergent per 100 cm 3This is calculated from the typical detergent pack suggestion of 100 cm 3 of detergent in a medium soil wash and machines using around 20 litres of water for the wash cycle. Biological washing powders contain enzymes that break down food stains. The reaction catalysed by two enzymes P and S used in biological washing powders.

Cleaning time using the power of enzymes STEAM. Enzyme activity arbitrary units Fig. The main component of washing powder is anionic surfactant.

Many biological washing powders contain enzymes to help with the removal of stains. Suggest how a biological washing powder removes this type of stain. The enzymes break down proteins or fats on the fabric forming water-soluble substances that can be washed away.

I Describe how the presence of these enzymes may increase the efficiency of the washing powder in removing stains from clothes. Biological washing powders contain enzymes. Answered expert verified.
