Certain Types of Cells Have Very Low Levels of Metabolic

question 220

Multiple Choice

Certain types of cells have very low levels of metabolic activity for long time periods, but then rapidly shift to grow and divide.To undergo this shift, these cells must activate anabolic pathways.Which is one way they are able to accomplish this?

• A) Large molecules influence metabolic flux through competitive inhibition effects on enzymes.
• B) Small molecules affect metabolic flux through allosteric effects on enzymes.
• C) Anabolic enzymes inhibit catabolic enzymes.
• D) Cells begin directing all of their energy toward reactions with negative  Gs.
• E) Cells only synthesize anabolic enzymes and cease synthesizing catabolic enzymes.
