Uses Of Enzymes Flashcards
At what temperature are biological detergents most affective?
At low temperatures ,30°
Why are the proteins in some baby foods pre digested using protein-guessing enzymes(protease)
The proteins in some baby foods are predigested using protein digestive enzymes so that they are easier for the baby to digest
What are carbohydrate digesting enzymes used for in terms of changing foods?
Carbohydrate digestive enzymes (carbohydrases) can be used to turn starch syrup into sugar syrup
Which enzyme is used to turn Glucose syrup into fructose syrup?
Isomerase enzyme
Why is glucose syrup turned into fructose syrup using an isomerase enzyme?
Fructose is sweeter so you can use a less of it which is a benefit for slimming foods and drinks
Why are enzymes useful in industry?
Enzymes speed up reactions without the need for high temperatures and pressures
Why is the lower temperatures an advantage of using enzymes in industry?
Lower temperatures and pressures means a lower cost as it saves energy
Enzymes work for a long time. Why is this an advantage for industries?
Enzymes work for a long time so after the initial cost of buying them you can continually use them
Why are enzymes beneficial in terms of environmental effects?
Enzymes are biodegradable and therefore cause less environmental pollution
How can biological washing powders be harmful in terms of enzymes?
Some people can develop allergies to the enzymes in washing powders
What is a disadvantage of enzymes in terms of temperature and pH?
Enzymes can be denatured by even a small increase in temperature. They are susceptible to poisons and changes in pH meaning that their conditions must be tightly controlled
Which enzymes are found in biological detergents?
Mainly protein digesting enzymes (protease)and fat digesting enzymes (lipase)
