a) i) Account for the shape of the graph between A and B.
ii) B and C
b) How can the rate of reaction be increased after point B?
c) State two other factors that affect the rate of enzyme reaction

  

Answers


John
a) i) Between A and B - Rapid/ fast increase in the rate of reaction. More active sites of enzymes available, for a large number of molecules of substrate; hence increase in the rate of reaction.

ii) Between B and C - Enzymes/ substrate are in equilibrium/ All active sites are occupied; hence rate of reaction is constant.

b) By raising concentration of enzymes and substrates.

c) pH, temperature, presence of inhibitors/ cofactor and co-enzymes
