1. Enzymes are biological molecules that act as catalysts in facilitating cellular processes.
2. Enzymes speed up chemical reactions by lowering the activation energy needed for the reaction to occur.
3. They do this by binding to specific substrates, creating an enzyme-substrate complex.
4. This complex undergoes structural changes that help to break or form chemical bonds in the substrates, leading to the reaction happening faster.
5. Enzymes are crucial for various cellular functions like metabolism, DNA replication, and protein synthesis.
6. An example is the enzyme amylase, which speeds up the breakdown of starch into sugars during digestion.
7. Overall, enzymes play a vital role in maintaining the efficiency of cellular processes by accelerating chemical reactions without being consumed in the process.
