Answer:
The ath operon is most likely controlled by the CAP and a repressor similar to the lac operon.
Explanation:
The CAP senses the low concentration of glucose and activates the transcription of the ath operon for it to metabolize the athelose and obtain energy. When the glucose is in high concentrations, the ath repressor, which works as a lac repressor, inhibits the transcription of the ath operon, it does this by binding to a part of the operon called operator getting in the ARN polymerase way and stoping the transcription. If there is glucose, the repressor binds to it and it is not bound to the operon allowing the transcription and metabolism of glucose.

Some organisms, such as plants, can trap the energy in sunlight through photosynthesis and store it in the chemical bonds of carbohydrate molecules. The principal carbohydrate formed through photosynthesis is glucose.

Answer:
Like other organs, leaves are often modified for functions other than photosynthesis. Tendrils of plants are leaves modified for support. In some plants the entire leaf is a tendril,
photosynthesis in these plants is delegated to leaflike structures called stipules at the base of each leaf.
