Metabolic pathways can be controlled through the availability of enzymes and modulation of their catalytic activities.Enzyme availability can be regulated via _______, while enzyme activity is commonly regulated via _______.

Question

Quizplus · Accepted Answer

Enzyme availability can be regulated via gene expression, while enzyme activity is commonly regulated via allosteric activation and inhibition. Covalent modification can also play a role in regulating enzyme activity, but it is not the most common mechanism. Proteolytic breakdown would lead to the degradation of the enzyme, which would not provide regulation of the metabolic pathway.
