Suppose a hypothetical enzyme hklase is able to break down, Ask an Expert

Academics

Suppose a hypothetical enzyme hklase is able to break down a hypothetical sugar hklose. Assume that the synthesis of hklase is controlled by an operon.
Briefly explain whether you predict the operon to be an inducible or a repressible operon. - I believe the operon is inducible since the hklase is involved in a catabolic pathway.
How would the presence of hklose effect the transcription of the genes that are involved in hklose degradation? (For clarity - you need to address the role of hklose, the repressor, and the operator). - I am confused with how the presence of the sugar affects the gene transcription. What are the repressors and the operators in this particular event?
