It depends on what ph Levoe you are exposing it to. For example, if you you take a protein that is usually in an alkaline (basic) solution and put it in an acidic solution, yes it will lose its shape.

Can the active site of an enzyme be damaged at very high pH levels?
The active site of an enzyme can very much be influenced and damaged by a very high pH level. An enzyme is a protein, and because of that it is very sensitive to pH levels. High pH can denature a protein, and thus "damage" the active site.
How does an enzyme become denatured?
An enzyme becomes denatured when: A) the temperature exceeds the optimum temperature for that enzyme (ie the temperature that it works best at) B) the pH of the surrounding of the enzyme is too low or too high for the optimum pH for that enzyme. When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape becomes broken. The enzyme shape changes and the substrate no longer fits in to the active site. An enzyme which has become denatured is permanently inactive and will take no further part in reactions.
Which gas will cause rainwater to have a pH of 6.0?
A PH of 7 is neutral, a PH falling below this means that the water is acidic. Carbon dioxide and SO2 are common gases found in the air which, when when dissolved in rainwater, will cause it to become acidic and thus lower the PH.
What might occur if pH blood level persisted outside the range?
If the pH blood level persisted outside the its normal range then the enzymes in the body will not operate and may even die This will cause the organisms to become ill or to die
PH values of acids?
Acids generally have a pH ranging from 1 - 6. pH 1 being the most acidic, and pH 6 being the least acidic. eg, hydrochloric acid, nitric aicd, sulfuric acid has a pH of 1. Ethanoic acid has a pH of 3.
A drastic conformational change in protein in response to conditions such as extreme heat pH will lead to loss of a protein function this drastic change in shape is called?
denaturation
What are 4 factors that can destroy the shape of a protein?
temperature,ph,
What is the word used to describe the distortion and inactivation of a protein by pH or heat?
Denatured protein. See attached Wikipedia Denatured Protein link. Denaturation. Proteins are fragile and its function depends on its 3D shape. High heat, salt concentration, pH, radiation etc will cause a protein to 'unravel' or change shape which leaves the protein nonfunctional. It is usually irreversible. Think of it as frying an egg. Eggs are protein right? When you fry an egg you change its shape and it is no longer opaque. You cannot unfry an egg.
How can a protein lose its tertiary structure?
affected by temperature or pH cause the protein denature .
Why does a protein not function after it has denatured?
Denaturation of a protein means loss of the protein's function due to structural change in the protein caused by some chemical or physical factor such as high temperature or unfavorable ph. The bonds that hold the structure together get affected which leads to the loss of structure and function
What is the term for a protein losing its 3D shape?
A protein is "denatured" when it inflates or deflates due to pH level, heat, Ect. Not sure if that's what you meant by losing its shape, though
The changes due to protein Denaturation?
High temperatures that go past the optimum temperatures usually leads to the denaturation of the protein. Denaturation of the proteins is usually as a result of the destruction of the tertiary and primary structures.
What is the pH in enzymes activity?
pH is a major determinant of protein structure. The function of a protein is directly related to its structure. For example, pepsin (a proteinase- a protein-digesting enzyme) is functional in the low pH of the stomach because the pH of the stomach provides a suitable environment for proper folding, interactions, and the overall shape of the protein. In the small intestine, where the pH is much higher, it has a significant decrease in activity because this is no longer a favorable environment for the protein.
How does acid rain effect protein shape?
The pH of the environment will change (it'll become more acidic) So the protein won't be able to interact the same therefore the shape will be changed
What happened to a protein that has become denatured?
A protein is denatured because of high temperatures or changes in pH. When it is denatured, it means that the protein has lost its original shape and therefore, it cannot function properly anymore.
What conditions can influence protein shape?
pH, pressure, past history, metal molecules, adjacent proteins.
What 4 factors can change the protein shape?
pH, temperature, presence of inhibiting proteins
