Chem4Kids : Biochemistry: Enzymes
Enzymes Make the World Go 'Round We have a whole section where we tell you about reactions and the molecules that change in those reactions. Chemical bonds are being created and destroyed over a series of many intermediate reactions.
"Lock and key" model. To explain the observed specificity of enzymes, in 1894 Emil Fischer proposed that both the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. This is often referred to as "the lock and key" model.
Enzyme kinetics is the study of the chemical reactions that are catalysed by enzymes. In enzyme kinetics, the reaction rate is measured and the effects of varying the conditions of the reaction are investigated.
Enzyme Kinetics University Science Books
CHAPTER 10 Enzyme Kinetics One of the most fascinating areas of study in chemical kinetics is enzyme catalysis. The phenomenon of enzyme catalysis usually results in a very large increase in reac
