Here's an example: When the salivary enzyme amylase binds to a starch, it catalyzes hydrolysis (the breakdown of a compound due to a reaction with water), resulting in maltose, or malt sugar. How Does 'Kinetic' Sand Work? How Does a Black Hole Form? Why Does the Earth Rotate? Origin...
How is enzyme activity regulated by the cell? How is the activity of an enzyme is regulated? How does substrate concentration affect enzyme activity? How does an enzyme work to catalyze a reaction? How does enzyme structure determine the function of the enzyme?
How does an enzyme immunoassay (EIA) test work?During EIA the process uses enzyme labelled antibodies and antigens to detect the small biological molecules required. The technique makes use of the basic immunology concept that an antigen binds a specific antibody. Such antigen molecules, which can...
Restriction enzymes- Many bacteria are able to produce restriction enzymes, which recognize very specific patterns in DNA chains and break the DNA at those patterns. When a virus injects its DNA into a bacterium, the restriction enzyme recognizes the viral DNA and cuts it, effectively destroying ...
What is an enzyme and how does it work? Explain the functions of enzymes. How does an enzyme work to catalyze a reaction? What is the difference between stomach acid and digestive enzymes? Where do enzymes go, after digestion? Are they excreted? If yes, then explain how, and are intra-...
There are several discrepancies in the current hydrogenase reaction model.We concluded that in H2-oxidizing reaction, there are 2 autocatalytic reaction steps.First autocatalytic step is in the activation process, it is simply an electron transfer.Second autocatalytic step is in the active cycle....
of enzyme, depending on how important a reaction is to a cell and how often the reaction is needed. These enzymes do everything from breaking glucose down for energy to building cell walls, constructing new enzymes and allowing the cell to reproduce. Enzymes do all of the work inside cells...

Another option is to linearize the DNA with an enzyme that is not resistant to supercoiling, then digest with the enzyme of choice. Alternatively, relax the DNA with topoisomerase, then digest with the restriction enzyme. Substrate DNA has many restriction sites per unit of mass The Promega Pr...
Blocks an enzyme in the liver, causing the liver to make less cholesterol Increases the uptake and breakdown by the liver of cholesterol already in the blood Along with diet, CRESTOR lowers bad (LDL) cholesterol and slows plaque buildup in arteries as part of a treatment plan to lower choles...
