Glucose

question 81

Multiple Choice

Glucose

• A) is preferentially used over lactose in E. coli as a result of catabolite repression AND levels are correlated with cAMP levels.
• B) is preferentially used over sucrose in E. coli as a result of catabolite repression AND levels are directly sensed via catabolite repression.
• C) is preferentially used over lactose in E. coli as a result of catabolite repression AND glucose levels are the inverse of cAMP levels.
• D) is preferentially used over lactose in E. coli as a result of catabolite repression AND levels directly affect the production of lactose dehydrogenase.
• E) is preferentially used over sucrose in E. coli as a result of catabolite repression AND levels are correlated with cAMP levels.

Definitions:

Average Cost Curve

A graph showing the cost per unit of output produced, calculated by dividing total costs by the quantity of output.

U‐Shaped

The U-shaped concept typically refers to a relationship where variables initially decrease, reach a lowest point, and then increase, forming a graph that resembles a U shape.

Long-Run Average Cost Curve

Shows the way per unit costs change with output in the long run.

Scale of Plant

The size or capacity of a single production facility or plant, which can affect its operational efficiency and production costs.
