The correct choice is (a) True
The best I can explain: Kinetic expressions requires both growth-associated and maintenance-associated production.
rP = qpx
rP = (YP/X μ + mP)X
qP = (YP/X μ + mP)
Where,
YP/X is the theoretical yield of product from biomass, mp is the specific rate of product formation due to maintenance, and x is biomass concentration.
