D)two of these

Question

Quizplus · Accepted Answer

Catabolite repression allows cells to save energy by not making unneeded enzymes (A) and also enables cells to prioritize the consumption of multiple substrates, typically preferring glucose over other carbon sources (B). This mechanism does not directly relate to cell growth after the preferred nutrient is used up (C), but rather to the efficiency and prioritization of nutrient utilization.
