Enzymes: Thoroughbred Workhorses of the Cell

  • Enzymes catalyze every chemical reaction that takes place in biology--from things as simple as the dissolving of carbon dioxide to reactions as complicated as the replication of the genetic material of DNA. Uses the analogy of a computer-controlled printing plant to explain the processes that enzymes control within a cell. Explores in detail the action of PFK (phospho fructose kinase) and explains specificity and catalysis. Computer graphics simulate the precise movements of the parts of the molecules involved in the reaction. Laboratory processes for isolating enzymes are described and x-ray crystallography is studied.
