What does the name of an enzyme tell us?
The name of an enzyme typically indicates its substrate or the type of reaction it catalyzes. Enzyme names often end in "-ase" to show that it is an enzyme. Additionally, the name may provide information about the enzyme's source or origin, such as "pepsin" from the stomach.
What kind of mechanism is the enzyme-subtrate complex often compared to?
The enzyme-substrate complex is often compared to a lock-and-key mechanism. In this analogy, the enzyme acts as the lock, and the substrate is the key that fits perfectly into the enzyme's active site. This specificity ensures that only particular substrates can bind to the enzyme, facilitating the biochemical reaction. Alternatively, the induced fit model also describes this interaction, suggesting that the enzyme can change shape to better accommodate the substrate upon binding.
What do you call the rate of an enzyme catalyzed reaction?
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
What are cofactors inhibitors and activators?
Cofactors are non-protein molecules that assist enzymes in catalyzing biochemical reactions, often by helping to stabilize enzyme-substrate complexes or contributing to the chemical reaction itself. Inhibitors are substances that decrease enzyme activity, either by binding to the enzyme or the enzyme-substrate complex, thereby preventing the reaction from occurring. Activators, on the other hand, enhance enzyme activity, often by promoting the binding of substrates or altering the enzyme's conformation to increase its efficiency. Together, cofactors, inhibitors, and activators play crucial roles in regulating metabolic pathways and enzyme function.
Does the allosteric effect in an enzyme change the enzyme's function?
Yes, the allosteric effect can change an enzyme's function by altering its activity or affinity for its substrate. This modulation is often achieved by a molecule binding to a site on the enzyme other than the active site, causing a conformational change that affects the enzyme's catalytic activity.
Is p-nitrophenol an enzyme?
No, p-nitrophenol is not an enzyme. It is a chemical compound that is often used in biochemical research as a substrate for enzyme assays.
What does the name of an enzyme tell us?
The name of an enzyme typically indicates its substrate or the type of reaction it catalyzes. Enzyme names often end in "-ase" to show that it is an enzyme. Additionally, the name may provide information about the enzyme's source or origin, such as "pepsin" from the stomach.
What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.
What kind of mechanism is the enzyme-subtrate complex often compared to?
The enzyme-substrate complex is often compared to a lock-and-key mechanism. In this analogy, the enzyme acts as the lock, and the substrate is the key that fits perfectly into the enzyme's active site. This specificity ensures that only particular substrates can bind to the enzyme, facilitating the biochemical reaction. Alternatively, the induced fit model also describes this interaction, suggesting that the enzyme can change shape to better accommodate the substrate upon binding.
What are the symbols ALP and GGT?
ALP stands for alkaline phosphatase, which is an enzyme found in the liver and bones. GGT stands for gamma-glutamyl transferase, another liver enzyme that helps in the metabolism of compounds in the liver. Both ALP and GGT levels are often measured in blood tests to assess liver function.
What is an enzyme called when it changes shape?
An enzyme is called a denatured enzyme once it changes its shape.
What do you call the rate of an enzyme catalyzed reaction?
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
How do competitive and noncompetitive inhibitions differ?
A competitive inhibitor often binds to an enzyme's active site. Noncompetitive inhibitors usually bind to a different site on the enzyme.
What are cofactors inhibitors and activators?
Cofactors are non-protein molecules that assist enzymes in catalyzing biochemical reactions, often by helping to stabilize enzyme-substrate complexes or contributing to the chemical reaction itself. Inhibitors are substances that decrease enzyme activity, either by binding to the enzyme or the enzyme-substrate complex, thereby preventing the reaction from occurring. Activators, on the other hand, enhance enzyme activity, often by promoting the binding of substrates or altering the enzyme's conformation to increase its efficiency. Together, cofactors, inhibitors, and activators play crucial roles in regulating metabolic pathways and enzyme function.
What name is used to describe the H-N-H groups?
The H-N-H motif is commonly associated with endonuclease enzymes that recognize specific DNA sequences and cleave the DNA at those sites. These enzymes are often referred to as H-N-H nucleases due to the arrangement of the histidine (H), asparagine (N), and histidine (H) residues in their active sites.
What is the product in protease?
Protease is an enzyme that facilitates the breakdown of proteins into smaller peptides or amino acids. It acts as a catalyst in various biological processes involving protein digestion and metabolism.
What does the medical abbreviation CKP mean?
CKP can stand for "creatinine kinase-MB" which is an enzyme found mainly in the heart muscle. It is often measured in blood tests to diagnose heart attacks.
