Sucrase denatures at approximately 50-60 degrees Celsius (122-140 Fahrenheit, and 323-333 kelvin)
I am pretty sure this is accurate for anyone who is struggling

What happens to the enzyme when it is cooled below its best working temperature?
When an enzyme coola below a temperature where it can work, it denatures (dies).
When enzymes are placed in extreme pH or temperature conditions they unwind and change shape This is called what?
The enzyme 'denatures'
What is the main purpose of a sucrase?
Sucrase is an enzyme which catalyze the hydrolysis of sucrose to fructose and glucose.
What is sucrase secreted from?
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.
What effect does freezing have on pepsin activity?
Heat affect any enzyme and so pepsin. A temperature about 80 degrees can degarade most of the proteins and pepsin. At this temperature pepsin loose its structure and can not be active after that.
How does a large change in temperature or PH effect proteins?
It denatures it.
What happens to the enzyme when it is cooled below its best working temperature?
When an enzyme coola below a temperature where it can work, it denatures (dies).
Why does the rise in temperature decrease the affinity of hemoglobin for oxygen?
The rise of temperature denatures the bond between oxygen and hemoglobin.
When enzymes are placed in extreme pH or temperature conditions they unwind and change shape This is called what?
The enzyme 'denatures'
What is the optimal pH of sucrase?
The optimum pH for sucrase is 2.0
What is the main purpose of a sucrase?
Sucrase is an enzyme which catalyze the hydrolysis of sucrose to fructose and glucose.
What temperature denatures lipase?
Lipase begins to denature at 70 degrees Celsius and is completely denatured at 85 degrees Celsius. Hope that this helps
What is sucrase secreted from?
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.
Where is sucrase secreted?
Sucrase is synthesized in the small intestine by the brush border, and secreted by the tips of the villi epithelium, particularly in the duodenum
What effect does freezing have on pepsin activity?
Heat affect any enzyme and so pepsin. A temperature about 80 degrees can degarade most of the proteins and pepsin. At this temperature pepsin loose its structure and can not be active after that.
What happens to the activity of an enzyme on either side of its temperature optimum?
Lower temperature: The energy input increases the flexibility of bonds in proteins. Higher temperature: Too much energy makes the bonds between the proteins brake and the protein unfolds 'denatures'
In today's experiment what was one method that you used to denature the catalase?
Allow the temperature to go above that catalysts/enzymes operational temperature. e.g. Yeast works at about 37 oC, however, it denatures above 45 oC.
