ENZYMES Biochemistry PowerPoint Slideshow
Enzymes are biological catalysts
Catalysts are substances that increase the speed of a chemical reaction, it is not permananetly changes, nor it does it cause the reaction to occur, that is, a catalyst can increase the speed of a reaction but cannot cause that reaction if it would not occur in the absence of catalyst. Since catalysts are not used up, they can be used over and over again.
