Enzymes are the "workhorses" of biology. Understanding how they function, how they are regulated, and what causes them to fail is foundational to biochemistry and medicine.
The specialized "pocket" or groove where the substrate binds. enzyme activity ppt download
A more modern view suggesting that the enzyme is flexible. When a substrate begins to bind, the enzyme changes its shape slightly to grip the substrate more tightly (like a glove molding to a hand). 3. Key Factors Affecting Enzyme Activity Enzymes are the "workhorses" of biology
These bind to a different part of the enzyme (the allosteric site), changing the enzyme's shape so the substrate can no longer fit. 5. Why Download an Enzyme Activity PPT? A more modern view suggesting that the enzyme is flexible
These mimic the substrate and "compete" for the active site.
Real-world examples like lactose intolerance or industrial enzyme use in detergents.
Increasing the substrate concentration increases the rate of reaction—but only up to a "saturation point" where all active sites are occupied.
