Organisms exhibit the characteristic of metabolism, a broad term that encompasses the processes undertaken to obtain and utilize energy. It is understood that humans require food, which contains various nutrients essential for cellular function. A significant category of these nutrients is carbohydrates, which furnish our cells with glucose.
Answer:
Option (A).
Explanation:
The lac operon system in bacteria elucidates the process of lactose metabolism within the cell. The initial operon system was identified by Jacob and Monod. An operon is characterized as a cluster of genes transcribed together as a single RNA unit.
When both glucose and lactose are available in the media, the bacterium favors metabolizing glucose. The presence of glucose is recognized by the bacterial cell as the CAP-cAMP complex is essential for transcription, and its levels are reduced in glucose's presence. This mechanism effectively halts the transcription of lactose genes even when lactose is available.
Consequently, the right answer is option (A).
