What do long chains of amino acid create?
Short chains of amino-acids are called polypeptides, while longer a-a chains become, and form, proteins.
When a molecule binds to an area of an enzyme that is not the active site and changes the shape of the enzyme so that it no longer can work this is called?
Denaturation
What do pH and temperature alter the activity of an enzyme?
Enzymes are proteins, and proteins are designed to exist at specific temperatures and pH levels. When the temperature or the pH of their environment changes, the interactions that hold the amino acids of the enzyme in its particular conformation cease to function. The protein simply "falls apart" into an unstructured assembly of amino acids (a polypeptide still, but no longer a true protein) and cannot fulfill its function; this is called denaturation. For most enzymes, this occurs with an increase in temperature or a decrease in pH from their standard physiological environment.
How are proteins denatured in an organic solvent?
Enzymes and proteins. Denaturation unravels them, ruining their structure and therefore their function.
Does denaturing a protein affect an enzyme?
Alcohol such as ethanol or methanol can denature proteins. This is why we sterile our hands after working with germs or pathogens. If there are pathogens in our hands by chance, they (proteins on the cell) can be denatured by this.
What does marked changes mean?
when a doctor or radiologist looks at a xray or scan of a joint or bone then he understand the way it is supposed to be configured to work correctly. if he easily recognises that the shape in the joints are no longer as they should be or if growths have speared that indicates changes.
What proteins are polymers formed from?
Proteins are polymers formed from amino acids. This term generally refers to chains longer than 50 amino acids, shorter chains are usually called polypeptides (or polypeptide chains).
What do long chains of amino acid create?
Short chains of amino-acids are called polypeptides, while longer a-a chains become, and form, proteins.
How amylase enzyme change on heating?
Most proteins including enzymes are very sensitive to heat. When heated it will break the bonds that give the protein its shape. The protein only functions because of its shape. So when we heat a protein/enzyme, it changes its shape and it no longer functions. This process is called denaturation.
What is the plasma outside the outside the capillaries?
Plasma outside of capillaries is no longer called plasma, its name changes to interstitial fluid.
When a molecule binds to an area of an enzyme that is not the active site and changes the shape of the enzyme so that it no longer can work this is called?
Denaturation
If a mature RBC no longer contains a nucleus what are the two major cell functions they can no longer perform?
Making proteins and mitosis.
What changes did the machine gun make?
Changes in tactics- a frontal assault was no longer a good tactic.
What is economic dislocation?
Changes in economy happen. The jobs that people have may no longer exist even after the recovery of the economy. In terms of employment, this is called economic dislocation.

What is a Pseudogene?
A pseudogene is a gene that has been disabled by mutation, and is no longer functional.
Things that do change?
One thing that changes it ice, when it melts it changes to water. No longer a solid, but a liquid.
