Question
Low Glucose Levels → Increase in ____ → Conformational Change in CAP → Binds Promoter Region → Increase in Transcription of Lactase Gene.
Answer
Low Glucose Levels → Increase in cAMP → Binds to CAP → Conformational Change in CAP → Binds Promoter Region → Increase in Transcription of Lactase Gene.
Note: Bacteria can digest lactose, but it is more energetically expensive than digesting glucose. Therefore, bacteria only want to use this option if lactose is high and glucose is low. The lac operon is induced by the presence of lactose; thus, these genes are only transcribed when it is useful to the cell.
