Which is the enzyme without protein?
Ribozyme is an enzyme made of ribonucleic acid (RNA).
What is the difference between a noncompetitive inhibitor and an allosteric inhibitor in enzyme regulation?
A noncompetitive inhibitor binds to an enzyme at a site other than the active site, while an allosteric inhibitor binds to a different site on the enzyme, causing a change in the enzyme's shape and reducing its activity.
The term ribozyme describes what property of RNA molecules?
A ribozyme is an RNA molecule that is capable of catalyzing a chemical reaction. Prior to the discovery of ribozymes, the only known biological catalysts were proteins called enzymes.
Is telomerase a ribozyme?
No, it is an enzyme. Some textbooks claim it to be a ribozyme, but it is definitely an cellular enzyme. It has a reverse transcriptase part and a rna part. it uses the rna part as a primer and elongates the 3' end of a DNA strand which has been shortened during replication. It is usually not expressed in eucryotic cells but is active in proliferating eucaryotic cells such as germ cells. In tumor cells telomerase may be re-activated and thus the cell proliferates unrestrainedly.
What is the difference between an allosteric inhibitor and a noncompetitive inhibitor in terms of their mechanisms of action on enzyme activity?
An allosteric inhibitor binds to a site on the enzyme that is different from the active site, causing a change in the enzyme's shape and reducing its activity. A noncompetitive inhibitor binds to either the enzyme or the enzyme-substrate complex, also reducing enzyme activity but without directly competing with the substrate for the active site.
what is the difference between Ribozyme and Abyzyme?
One difference is how they are spelled.
What is difference between ribozyme and abzyme?
Ribozymes are RNA molecules that can act as enzymes to catalyze chemical reactions, while abzymes are antibodies that have enzymatic activity. Ribozymes are made of RNA, while abzymes are made of proteins. Both can catalyze specific reactions, but they differ in their structure and composition.
Which is the enzyme without protein?
Ribozyme is an enzyme made of ribonucleic acid (RNA).
What is the name of the enzyme that causes the formation of the peptide bonds between amino acids during translation of protein synthesis?
The enzyme responsible for forming peptide bonds between amino acids during protein synthesis is called peptidyl transferase. It is a ribozyme found in the ribosome.
What is the difference between enzyme and non enzymatic reactions?
A nonenzymatic reaction doesn't use an enzyme.
Whart is the difference between co factors and co enzymes?
co factor helps the factor in reaction and co enzyme helps the enzyme only
What is the difference between abzyme and enzyme?
enzyme is a kind of protein that catalyzes specific reactions & abzymes are antibodies that target the transition state of an expected reaction.
What difference between renin and rennin?
Rennin : It is an enzyme (protein) secreted by kidneys to regulate the blood pressure. It's a digestive enzyme in gastric juice. Renin :It is a hormone.
which only one enzyme is non protein in nature?
Pepsin) whereas other enzymes are composed of both protein part and non-protein part. The complete enzyme molecule (with both protein part and non-protein part) is known as holo-enzyme. The protein part is known as Apo-enzyme Non- protein part may be co-factor or co-enzyme
What is the difference between a noncompetitive inhibitor and an allosteric inhibitor in enzyme regulation?
A noncompetitive inhibitor binds to an enzyme at a site other than the active site, while an allosteric inhibitor binds to a different site on the enzyme, causing a change in the enzyme's shape and reducing its activity.
Enzyme which is not a protein?
Until the 1980s, researchers believed all enzymes consisted of protein. However, a molecule known as ribonucleic acid, or RNA, can also function as an enzyme. RNA is involved in protein synthesis within your cells, and, during the process, it can catalyze a reaction on itself or on another RNA molecule to splice unneeded material from the molecule and rejoin the cut ends. When RNA functions in this capacity, it is known as a ribozyme. Since the discovery of the first ribozyme, biochemists have found many more of these cut-and-paste enzymes within cells.
What is the difference between enzymes and catalyst?
There is no difference. An enzyme is a natural catalyst. Catalysts speed up the rate of reaction without being used up itself.
