WebHigher temperatures are more likely to increase enzyme activity's effect, while lower temperatures will decrease enzyme reaction rate. Higher temperatures result in more molecules colliding, which increases the likelihood that an enzyme collides with its substrate. The enzyme cannot bind to its substrate if it changes in shape. WebCooperative enzymes are more sensitive in their response to changes in substrate concentrations than other enzymes and display a “switch-like” transition from low to high reaction rate as substrate concentration increases. This corresponds to a velocity vs. substrate curve that is S-shaped, as shown above. [References] Sort by: Top Voted …
