Enzymes are vital biological catalysts that accelerate biochemical reactions, ensuring the sustenance of life. They are highly specific, acting on particular substrates with their unique active sites, and are involved in various functions such as DNA replication, metabolism, and digestion. Enzymes lower activation energy, enabling efficient reaction processes, and are essential in both anabolic and catabolic pathways. Their influence extends beyond natural systems to healthcare and industry.

Enzymes are specialized proteins with a unique three-dimensional structure that allows them to act as biological catalysts
Lock and Key Model
Enzymes have a specific active site that only allows the correct substrate to bind, similar to a lock and key mechanism
Induced Fit Model
Enzymes can also undergo a conformational change to fit the substrate, as proposed by the induced fit model
Enzymes regulate and facilitate biochemical reactions within cells, dictating the flow and sequence of metabolic pathways
Enzymes remain unchanged after participating in reactions and are highly sensitive to environmental conditions, making them efficient catalysts
Enzymes like DNA polymerase not only synthesize new strands of DNA but also possess proofreading capabilities to minimize errors and mutations
Enzymes often require cofactors or coenzymes to facilitate a wide range of life-sustaining processes
Enzymes play a crucial role in both anabolic and catabolic reactions in metabolism, facilitating the conversion of molecules within the cell
Digestion
Enzymes break down complex molecules during digestion, such as starches, proteins, and lipids
Energy Production
Enzymes are essential in cellular respiration, extracting energy from nutrients like glucose
Protection from Pathogens
Enzymes play a role in synthesizing biomolecules and protecting the organism from pathogens
Enzymes are involved in combating diseases and metabolizing pharmaceuticals in the liver
Enzymes are harnessed for their specificity and ability to operate under mild conditions in biotechnology and contribute to environmental sustainability by breaking down organic waste
