The genetic control strategy of enzyme control is most useful for production of enzymes that
options: a) act as hydrolases. b) function for only one specific reaction. c) are produced as zymogens. d) require vitamins as cofactors. e) are needed only at certain stages of development.
The correct answer and explanation is:
The correct answer is e) are needed only at certain stages of development.
Genetic control of enzyme production is a strategy employed by cells to regulate the synthesis of enzymes in response to environmental or developmental cues. This regulation is particularly important for enzymes that are needed only at specific points in an organism’s life cycle, such as during particular stages of development or in response to environmental changes.
Enzymes that are required only at certain stages of development are typically produced in a regulated manner, where their synthesis is controlled by genetic mechanisms. This can include processes such as the activation of specific genes at certain stages, or the modification of gene expression in response to external signals. For example, enzymes involved in fetal development are only produced during gestation and are not needed once the organism reaches maturity.
This type of genetic control ensures that resources are not wasted by producing enzymes that are not required at a given time, and it allows the organism to adapt its metabolic processes in response to its developmental needs. In contrast, enzymes that are always needed for basic cellular functions, such as hydrolases (answer choice a), or those that perform highly specific reactions (answer choice b), may not require such stringent regulation.
The other options, such as enzymes produced as zymogens (answer choice c) or those that require vitamins as cofactors (answer choice d), involve different mechanisms of enzyme activation and function but are not directly related to the strategic regulation of enzyme production during specific developmental stages. Therefore, the genetic control strategy is most useful for enzymes that are needed only at certain stages of development.
