Assembling the individual enzymes required for a multistep p

Assembling the individual enzymes required for a multistep process into a protein machine is likely to increase the efficiency with which the entire process is carried out in all of the following ways EXCEPT:

by increasing the rate at which the individual enzymes encounter their substrates.

by ordering the reactions sequentially.

by increasing the V_max of the individual enzymes.

by coordinating the regulation of the individual enzymes.

by coordinating the movement of the enzymes.

Solution

c). by increasing the V_max of the individual enzymes.

Vmax is the ceiling that limits the rate at which an enzyme can convert a substrate into a product. Vmax is the maximum velocity at which a reaction can occur, beyond the Vmax value, the rate of reaction do not increase with the increase in substrate concentration becuase the enzyme is saturated. Increasing the rate at which the individual enzymes encounter their substrates can help to increase the efficiency of a multistep process, but increasing the Vmax.
