An Introduction to Metabolism


  • Enzymes speed up metabolic reactions by lowering energy barriers
  • Enzymes are substrate specific
  • The activation site is in the enzyme's catalytic center
  • A cell's physical and chemical environment affect enzyme activity.
  • Organic Compounds= living system, questions about how life takes the step from chemicals to life
  • Chemistry of living has to be controlled, this control comes from enzymes
  • Nonliving things do not have to be controlled
  • Reactions occur fast enough to keep us alive thanks to enzymes
