Secondary Sugars(metabolism/sugar/bacteria/Lac Operon)

... that seemed to be of use; that secondary sugars might be sugars the require cAMP and CRP to be the effector of the operon(along with the operon inducer of course). Since gallactose is what the cell wants the most then the other metabolic operons(like lactose) should be off so any sugar that ...

DIFFERENT BETWEEN REPRESSOR AND INDUCER

Activator and repressor bind DNA. Activator = transcription; repressor = no transcription (simplified). Inducer does NOT bind DNA. Inducer binds either activator OR repressor. It makes activator BETTER able to bind DNA = more transcription OR it makes repressor LESS able to ...

Re: Why are flowers "beautiful"?

... a receptor to a pleasurable sensation. The fact that anything that activates the receptor, whether or not they are the right molecule or a neutral inducer (say a sweetener like aspartame) that do not fulfill any need would be a good proof that only the receptor activation is necessary. Concepts ...
