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.
