Enzymes Flashcards
What is the protease in baby food useful?
It breaks down protein into amino acids, this means they absorb the amino acids allowing them to get the nutrients they need out of their food.
What is the enzyme used to remove a blood stain?
Proteases, they break down the stain into water- soluble substances, these can be dissolved and washed away.
Explain what happens to enzymes when they are denatured.
This means they can no longer catalyse a reaction. They lose their specific shape to match the other shape of the substance they are acting on meaning they can’t stick and are permanently changed.
Complete-
__________ are a type of _______. They are used in reactions in industry. For example, ______ are used in washing powder to digest fat stains. If an enzyme is heated too much it will be _______.
ENZYMES are a type of CATALYST. They are used in reactions in industry.for example PROTEASES are used in washing powders to remove fat stains.If the enzyme is heated too much it will be DENATURED.
State what helps making fruit juice.
Pectinase is added to pectin ( from apples and oranges) which makes it easier to break down the cell walls and to squeeze, releasing more juice.
How are enzymes affected by temperature? Explain how this affects your use of biological washing powders.
The higher the temperature the higher the reaction, this is true till you reach an optimum temperature, where afterwards it becomes too hot and the enzyme is denatured. This could affect your use of washing powder because it may not clean your clothes after a certain temperature.
