Some household products use enzymes to speed up the chemical reactions: enzymes in biological washing powders breakdown protein, starch or fat stains on clothes and, enzymes in meat tenderizer break down proteins into smaller molecules, making the
29-06-2020·Biological washing powder works by adding enzymes to the washing powder. Stains are made of different molecules and the enzymes helps in breaking them down. The enzymes used are amylases used to break down starch, proteases used to break down protein and lipase used to break down grease and fats.

Mechanical digestion is the physical process of preparing the food for chemical digestion.. It involves chewing (in the mouth), mixing, churning (in the stomach and intestine) and segmentation (in the intestine).; Large pieces of food are breaking down into smaller pieces à increases the surface area of the food.; Bile physically digests fats by emulsifying them – …
03-12-2012·You name a biological process and enzymes are probably involved in it. That’s why the washing powders that contain them are ‘biological’. The enzymes that are added to washing powders are like molecular scissors that chop up fats, starch and proteins, all of which cause stains on your clothes.

Seeds contain stored food in the cotyledons to provide energy and materials for growth.This is usually in the form of starch – a large, insoluble molecule (long chain of glucose), that keeps the food immobile.The starch needs to be changed into a soluble molecule (sugar) with help of enzymes for the seeds to make use of.
Protease enzymes are secreted by the stomach, pancreas and small intestine and their job is to digest proteins. An example of a protease is pepsin which is secreted in the stomach. Proteins are long chains of amino acids, and protease enzymes break them into peptides (smaller chains of amino acids molecules) and eventually into individual amino acids , which are small and …
A Enzymes help prevent the breakdown of clothing fibers, so clothes last longer. B Enzymes can reduce the amount of water needed in a washing machine. C Washing powders with enzymes smell nicer than washing powders without enzymes. D Enzymes can help break down and remove stains caused by food.
Biological detergents contain protease enzymes. (a) ... These enzymes help to digest food in the human digestive system. Each enzyme is produced by a different part of the digestive system. Kingsmead Technology College ... accept amylase only breaks down / digests starch 1
21-07-2020·Uses of Enzyme in Biological Washing Powder (Protease) Washing powders contain detergents that remove stains from clothes by dissolving them in water. However, some stains are made up of insoluble …
11-10-2011·Biological detergent (washing powder): Proteases, amylases and lipases are used to remove protein, starch and oily stains from clothes. Brewing (beer): Proteases in barley are released as it is fermented during beer production. The enzymes break-down starch, carbohydrases and proteins, and clarify stored beers.
There are enzymes in biological washing powders. Biological washing powder has to be used at temperatures below 45 °C. (a) The enzymes in biological washing powders do not work on the stains on clothes at temperatures above 45 °C. Explain why.
25-03-2019·By washing a variety of stains with detergents to which they have added different ‘mystery’ enzymes, students guess the enzyme type based on the effectiveness of the detergents they have created. In addition, students test their detergents at three different temperatures to examine how this affects the performance and to see that some enzymes are …
20-09-2012·Amylases break down starches; and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.
