What is a negative result for troponin test?
Troponin is a cardiac enzyme that your heart releases under stress.
What does it mean when an enzyme has a low value for its Michaelis constant?
It indicates that the enzyme has a high affinity for the substrate.
What 3 letter in the enzyme name tells that it is an enzyme?
The suffix -ase indicates an enzyme, e.g. proteinase, dehydrogenase, hydrogenase, polymerase.
How does a biological negative feedback loop work?
Negative Feedback: Enzyme A makes Substance A when Substance A is not available in the Diet. When Substance A becomes available in the Diet, Enzyme A is no longer required and The Negative Feedback loop shuts down the production of Enzyme A.
What color for cardiac enzyme blood draws?
The tubes used for cardiac enzyme blood draws are typically red or tiger-topped tubes, which contain a clot activator and a gel separator. These tubes are used for testing cardiac enzymes like troponin, creatine kinase (CK), and CK-MB levels.
What is the abbreviation for electrocardiogram?
the abbreviation for Electrocardiogram is either EKG or ECG
What 3 letters in the enzyme's name tells that it is an enzyme?
The suffix -ase indicates an enzyme, e.g. proteinase, dehydrogenase, hydrogenase, polymerase.
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 color is the tube top for cardiac enzyme test?
The color of the tube top for a cardiac enzyme test is typically red or gold. These colors indicate that the tube contains a gel separator and clot activator to help with blood separation and clotting.
What is the proper order of draw fpr pt ptt cbc ammonia levels and cardiac enzymes?
the proper order of draw for pt /ptt/ ,cbc ammonia and cardiac enzyme the multi -draw method which is
What is the relationship between the kinetic constants kcat and Km in enzyme catalysis?
In enzyme catalysis, the kinetic constant kcat represents the turnover number, or the rate at which an enzyme can convert substrate into product. The Michaelis constant Km represents the substrate concentration at which the enzyme works at half of its maximum speed. The relationship between kcat and Km is important because it helps determine the efficiency of an enzyme. Generally, a lower Km value indicates a higher affinity of the enzyme for its substrate, while a higher kcat value indicates a faster turnover rate.
What does the enzyme graph reveal about the reaction rate of the catalyzed reaction?
The enzyme graph shows that the reaction rate of the catalyzed reaction is faster compared to the uncatalyzed reaction. This indicates that the enzyme is effectively speeding up the reaction process.
