The Induced Fit Model of enzyme action is a key concept in biochemistry, detailing how enzymes adapt their shape to bind substrates and catalyze reactions. Unlike the static Lock and Key Model, this dynamic model explains the enzyme's structural flexibility and its ability to lower activation energy, thus enhancing catalysis. It underscores the importance of conformational changes in enzyme specificity and adaptability, providing a deeper understanding of biochemical processes.

Difference between Induced Fit and Lock and Key Models
Induced Fit implies flexible active sites adapting to substrates, while Lock and Key suggests static, unchanging active sites.
01
Conformational changes in enzymes during catalysis
Enzymes undergo shape changes to form precise fit with substrate, enhancing catalytic efficiency.
02
Enzyme's state post-catalytic reaction
After catalysis, enzyme reverts to original shape, ready to interact with new substrate molecules.
