← ScienceWhich consequence results when molecular steric hindrance limits enzyme-substrate complex formation?
A)Reduced catalytic reaction velocity✓
B)Increased activation energy barrier
C)Altered enzyme conformational flexibility
D)Greater allosteric binding efficiency
💡 Explanation
Reduced catalytic velocity occurs because steric hindrance prevents substrates from positioning properly within the active site, inhibiting the enzyme's action. Therefore, the reaction rate slows rather than enhancement or allosteric modification under idealized conditions for optimal throughput.
