Front

During which stage of the bacterial growth curve is the specific growth rate constant and highest?

Back

Log phase

Front

In the lag phase, which of the following activities are NOT occurring? Synthesis of RNA and ribosomes, Adaptation to the new environment, Synthesis of essential enzymes and metabolites, Cell division, Increased respiration rate

Back

Cell division

Front

Which two phases of the bacterial growth curve are characterized by a relatively constant number of viable cells?

Back

Stationary and Death phases

Front

In a nutrient-limiting environment, what is the primary factor responsible for the transition from Log phase to Stationary phase?

Back

Depletion of essential nutrients

Front

Which term does NOT accurately describe the Death phase of a bacterial growth curve? Options: Exponential decline in viable cell number, Increased susceptibility to environmental stress, Accumulation of cellular debris, Activation of cell repair mechanisms, Decrease in metabolic activity

Back

Activation of cell repair mechanisms

Front

A researcher observes a prolonged lag phase in a bacterial culture inoculated into a new medium. What is the most likely explanation?

Back

The medium is deficient in essential nutrients.

Front

Two bacterial cultures grown under identical conditions exhibit different Log phase slopes. What could explain this difference?

Back

All of the above

Front

Which factor would NOT significantly affect the shape of a bacterial growth curve?

Back
