Final answer:
True, branch pathways require sophisticated regulation because they can be regulated by feedback control to prevent waste of substrate and conserve energy.
Step-by-step explanation:
Branch pathways do require sophisticated regulation, so the statement is true.
Metabolic pathways in cells involve a series of reactions catalyzed by multiple enzymes. These pathways can be regulated by feedback control, where the product of one step in the pathway feedbacks to an earlier step to increase or decrease production. This feedback control helps to prevent waste of substrate and conserve energy.
For example, in feedback inhibition, if too much product is formed, it can bind to an enzyme involved in an earlier step to inhibit the formation of subsequent products. This type of regulation prevents the production of unnecessary products and saves cellular resources.
