Enzymes

Biochemistry 3070. Enzymes. Enzymes. Enzymes are biological catalysts. Recall that by definition, catalysts alter the rates of chemical reactions but are neither formed nor consumed during the reactions they catalyze. Enzymes are the most sophisticated catalysts known.

Enzyme Kinetics

Enzyme Kinetics. Enzymes are proteins that can accelerate biochemical reactions by factors of 10 5 to 10 17 ! This is much higher than chemical catalysts. Enzymes can be extremely specific in terms of reaction substrates and products.
