Answer:
Option B, not phosphorylated; inhibited
Explanation:
Glucose 6 acts as a catobolite repressant . A catobolite repressant which is usually a carbon compound inhibits the operon transcription. In the presence of glucose -6, unphosphorylated enzyme IIAGlc inhibits the transportation system and hence prevents the utilization of lactose. Glucose‐6‐phosphate and other non‐PTS carbon causes inducer exclusion thereby leading to dephosphorylation of enzyme IIAGl without getting transported.
Hence, option B is correct

Question :What are forms of cell regulation
Answer: Regulator Molecules of the Cell Cycle. In addition to the internally controlled checkpoints, there are two groups of intracellular molecules that regulate the cell cycle. These regulatory molecules either promote progress of the cell to the next phase (positive regulation) or halt the cycle (negative regulation).
Remember: Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.
The answer is hydrolysis.
The word hydrolysis comes from two Greek words:
hydro - water
lysis - to unbind
So, hydrolysis is a reaction of breaking apart (unbinding) large molecules using water. For example, sucrose or table sugar is disaccharide made of two monosaccharides: fructose and glucose. Hydrolysis of sucrose means that water molecule break apart sucrose, i.e. unbind fructose and glucose.
