Regulation of a hypothetical operon

Drag the labels onto the diagram to identify the small molecules and the states of the regulatory proteins. Not all labels will be used.

For positive control, (a) will be the inactive activator, (b) will be cAMP, and (c) will be the active activator. In other words, the process won't proceed unless the activator has a molecule bound to it. And the specific molecule necessary, in this case, will be cyclic AMP.

For negative control, (d) will be the active repressor that is MISSING a molecule, (e) will be athelose, and (f) will be the inactive repressor which HAS a molecule attached to it. In other words, this process will be repressed unless a specific molecule attaches to the active repressor to allow the process to start. The specific molecule necessary, in this case, will be athelose. Once it binds to the repressor, the repressor will detach and become inactivated, allowing the process to start.
