Only specific substrate(s) will fit into active site of enzyme
Malonate is an inhibitor of the enzyme succinate dehydrogenase. How would you determine whether malonate is a competitive or noncompetitive inhibitor?
presence of malonate, increase concentration of normal substrate (succinate) and if rate of reaction increases malonate is a competitive inhibitor.
Many spontaneous reactions occur very slowly. Why don't all spontaneous reactions occur instantly?
spontaneous reaction is exergonic. if it has high activation energy, rate of reaction may be low.
