Two reasons Why in vitro analysis may not give an accurate indication of an enzymes true biological action?
In vitro analysis does not consider the enzyme's interactions with cellular components or other enzymes present in a living system, hence the true biological action may be different. Also, the conditions in vitro may not fully replicate the native environment of the enzyme, affecting its functionality and activity compared to its in vivo state.
Why is denatured sucrase used as a control?
Denatured sucrase is used as a control because it allows researchers to observe the effects of denaturation on the enzyme's function. By comparing the activity of denatured sucrase to its native form, researchers can determine the enzyme's sensitivity to changes in temperature, pH, or other environmental factors. This control helps to ensure that any observed effects on sucrase activity are indeed due to denaturation and not other variables.
What are the effects of denaturation?
Denaturation disrupts the structure of proteins, causing them to lose their native conformation, and consequently their biological activity. This can be triggered by changes in temperature, pH, or exposure to chemicals, leading to loss of function in the denatured protein.
If an enzyme solution is frozen is the enzyme denatured?
No, freezing does not denature enzymes, however; it does slow the rate at which they are able to catalyse reactions. Denaturation is a permanent change in the conformation of an enzyme that renders it useless while freezing an enzyme only results in a temporary change.
What happen to an enzyme when it is boiled?
When an enzyme is boiled, its three-dimensional structure is disrupted and it denatures. This leads to the loss of its catalytic activity since the active site no longer matches the substrate. Once denatured, the enzyme cannot function properly and is typically rendered inactive.
When it loses its native confirmation and its biological activity?
Denatured
How do changes in pH and temperature affect the native confirmation of an enzyme?
Changes in pH and temperature can disrupt the bonds that hold the enzyme in its native conformation. This can lead to denaturation of the enzyme, resulting in loss of its catalytic activity. Each enzyme has an optimal pH and temperature at which it functions best, and deviations from these conditions can affect enzyme structure and function.

How does the addition of urea affect the rate of enzyme reaction?
Urea denatures the enzyme as it disrupts the 3-D structure of the enzyme, this changes the shape of the enzymes' active site, thus meaning that the enzyme is unable to create an enzyme-substrate complex which then means that the reaction cannot occur thus the rate of the enzyme controlled reaction becomes very slow.

Introduced species can have important effects on biological communities by?
Preying upon native species competing with native species for resources displacing native species :)

What is biological plants and animals that have migrated to place where they are not native are called?
They are called an invasive species.
What is native fold?
The native fold refers to the specific three-dimensional shape a protein molecule adopts when it is functioning properly in a biological system. This folded structure is essential for the protein to carry out its biological functions effectively. Any deviation from the native fold can lead to protein misfolding and potential loss of function or disease.
If you were born in Anchorage Alaska does that make you a native?
It makes you a native of Alaska, just like being born in Florida makes you a native of Florida. However, it does not mean you're a Native American--that has nothing to do with where you are born, but what your biological heritage is.
What is a native spiesies?
One that evolved in the place where it is found. A non native species is one imported from elsewhere by the activity of man.
