Study Notes
Microbial Enzymes
- Enzymes act as catalysts, speeding up chemical reactions vital for bacterial survival.
- Bacteria utilize enzymes to decompose organic materials and generate necessary energy and building blocks.
- Enzymes remain unchanged after facilitating reactions, allowing them to be reused multiple times.
Metabolites
- Bacterial growth and metabolism yield by-products known as metabolites.
- Metabolites are often waste products released into the environment as bacteria break down nutrients.
- Streptococcus mutans, a bacterium linked to dental caries, creates acids that erode tooth enamel, demonstrating the role of metabolites in health and disease.
