Enzymes:

  • Enzymes are biological molecules that act as catalysts in biochemical reactions.

  • They speed up reactions by lowering the activation energy, making them occur at biologically relevant rates.

  • Enzymes are highly specific, each catalyzing a particular reaction with specific substrates.

  • They have a three-dimensional structure, with an active site where substrates bind for catalysis.

  • Enzymes are sensitive to factors like temperature, pH, substrate concentration, and the presence of cofactors or inhibitors.

  • Enzyme activity is crucial for various biological processes, such as digestion, energy production, and DNA replication.

  • Regulation of enzyme activity is essential for maintaining the balance of biochemical reactions in living organisms.
