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.
