Enzyme activity refers to the measure of how efficiently an enzyme catalyzes a specific biochemical reaction. Enzymes are proteins that act as biological catalysts, speeding up chemical reactions within cells. Enzyme activity can be influenced by various factors such as substrate concentration, pH, temperature, and the presence of cofactors or inhibitors. Research in this area aims to understand the mechanisms by which enzymes function and how their activity can be regulated. This knowledge is important for a wide range of fields including medicine, biotechnology, and agriculture.
