The definition of enzyme?
an enzyme is a complex protein that cause a specific chemical change in other substances, without being changed themselves.
What two things can negatively affect the shape or function of an enzyme?
The most effective cause of their nonfunction or unefficiency is denaturation that is to lose their native conformation by heat or some detergent and second is the environment provided as to function properly protein needs specific pH, temprature etc.
When a protein such as an enzyme is subjected to too much heat?
The enzyme denatures, the internal bonds break. This means that the active site changes shape. This is because the arrangement of the secondary structures change After overheating an enzyme it is unusable
What can cause an enzyme to be denatured?
Heat
What is responsible for unwinding and unzipping the double helix?
To 'unwind' the double helix for protein synthesis, enzymes called DNA Helicases cause the two parent DNA strands to unwind and separate from one another in both directions. And im only 15
What can cause an enzyme to lose its confirmation?
When a protein is denatured, this can cause an enzyme to lose its confirmation.
3 variables that can cause an enzyme to lose its ability to function?
An enzyme is a catalyst for chemical reactions. Three variables that can cause an enzyme to lose its ability to function are temperature, pH level and concentration.
Which is the enzyme without protein?
Ribozyme is an enzyme made of ribonucleic acid (RNA).
The definition of enzyme?
an enzyme is a complex protein that cause a specific chemical change in other substances, without being changed themselves.
How does heat denature enzymes?
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.

If a gene was changed by mutation then what do you think would happen to the shape of enzyme built by the gene?
There are many possibilities. If the mutations occurs but it does not change the amino acid sequence due to the redundancy (codon degeneracy) of the genetic code, then the mutation is silent and no effect is observed. If the mutation occurs and the amino acid sequence is changed, but the new amino acid has similar properties to the original amino acid (e.g. aspartic acid -> glutamic acid) and the position of the mutation is far away from the active site, then the mutation will likely have minimal effects on the structure and function of the protein. However, if the mutation changes the amino acid sequence such that the new amino acid has a very different property to the original (lysine -> valine) or if the mutation occured close to the acitive site, then it is very likely that the structure and function of the protein will be compromised. Lastly, there is also the marginal chance that the last type of mutation described above actually increases the effectiveness of the protein. Though this is exceedingly rare, it is the driving force behind evolution.
What is the function of pancreatic amylase in human digestive system?
The primary function of the enzyme amylase is to break down starches in food so that they can be used by the body. Amylase testing is usually done to determine the cause of sudden abdominal pain.
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.
Which Enzyme function is true Enzymes cannot function at a pH lower than 6.Most coenzymes are inorganic substances such as ions of iron or potassium.Excessive salt ions can cause an enzyme to denature?
The answer is: "Excessive salt ions can cause an enzyme to denature." Although most enzymes function near neutrality, in the range of pH 6-8, there are some exceptions. For example, Pepsin, a digestive enzyme, works best at pH 2. While some coenzymes are inorganic, there are several organic coenzymes as well.
What does it mean to denature an enzyme?
The dependence of protein function on a protein's specific shape becomes clear when proteins are altered. Denaturation is the process by which proteins lose their structure and function because of an outside factor, such as a change in temperature or pH.
Why does pH denature enzymes?
If the temperature is increased then the enzyme becomes denatured. This happens at about 50-60 degrees in the human body. When enzymes are heated up too much they vibrate so vigorously that the bonds holding the protein structure in its specific shape break. 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.
