Factors Affecting Enzyme Action (AQA A-Level Biology): Flashcards

Irreversible loss of enzyme shape and function

Temperature where enzyme works best

pH where enzyme functions most effectively

Maximum velocity when all active sites saturated

Complementary, like lock and key

Raises kinetic energy, more collisions

$pH = -\log_{10}[H^+]$

More active sites, higher rate

All active sites occupied, reaches Vmax

No, it is permanent and irreversible
