By Michael W Bowers CKMB 3hr peak 1224hr lasts 13 days Troponin 312 hrs peak 1224hr lasts 821 days TropT and 714 TropI What is Creatine Kinase What is Creatine Kinase Creatine kinase is an enzyme . Mike Clark, M.D.. Isozymes. (also known as . isoenzymes. ) are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. These enzymes usually display different kinetic parameters (e.g. different . IMPORTANCE. OF ENZYMES. Enzymes are biological catalysts that:. . I. ncrease. . reaction rates . by lowering the amount of energy needed for the reaction to occur. 100-1000x . faster. !!!. Activation Energy. 1. What are enzymes?. Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over. protein. !. Enzymes are . Biological . catalysts . that . increase. . the rate of metabolic reactions.. Since enzymes speed up chemical reaction rates, what are they called?. Catalyst- . A substance . Part 1. . Chapter 3. Learning outcomes. You should be able to:. explain how enzymes work. describe and explain the factors that affect. enzyme activity. use V. max. and K. m. to compare the affinity of different enzymes for their substrates.

With liver injury, these enzymes may leak into plasma and can . Enzyme & Substrate. An enzyme is a globular protein which acts as a biological catalyst by speeding up the rate of chemical reactions. . Enzymes are .
