← ScienceWhich mechanism limits the rate of enzymatic digestion?
A)Substrate diffusion limits reaction velocity✓
B)Product inhibition shuts down catalysis
C)Enzyme denaturation eliminates active sites
D)Cofactor depletion stalls mechanism
💡 Explanation
Substrate diffusion to the enzyme active site limits turnover because Michaelis-Menten kinetics dictate maximum rate depends on collision frequency therefore, this limits overall reaction, rather than product altering enzyme activity under specified conditions.
