Enzymes and their properties Flashcards
what is the first property of enzymes
each enzyme only digests a specific type of nutrient
what is an example of the first property
an enzyme only digests carbohydrates but not fats or proteins
what is the second property of enzymes
enzymes are affected by temperature
what happens if the temperatures of enzymes is too high or too low
they will not work well or stop working
what happens when the temperature is too low
the enzymes are less active and the rate of reaction is low
what happens when the temperature is increasing
the enzymes will become active and the rate of reaction increases
what happens to the enzymes when the temperature is optimum
the enzymes are most active and the rate of reaction is the highest
what happens when the temperature is above optimum
the enzyme’s activity slowly decreases as the temperature increases
wat happens if the temperature is higher
the enzyme is destroyed and the enzymes will not be able to digest in food
what is the third property of enzymes
enzymes are affected by pH
- different enzymes work well at different pH
what is the pH of enzymes from the stomach
2 ( acidic )
what is the pH of enzymes from saliva
6.5 ( slightly acidic )
what is the pH of enzymes from small intestine
8 ( alkaline )
What are the 3 properties of enzymes
- each enzyme only digests a specific type of nutrient
- enzymes are affected by temperature
- enzymes are affected by their pH
