topic 3-Bacterial Growth Phases Flashcard

Front

What is generation time in bacterial growth?

Back

The time required for the population to double.

Front

What causes the lag phase in bacterial growth?

Back

Adaptation to a new environment.

Front

Which phase follows the exponential phase in a bacterial growth curve?

Back

Stationary phase.

Front

What is the primary difference between the stationary phase and the death phase?

Back

Net change in viable cell number.

Front

In which phase of bacterial growth is the rate of protein synthesis highest?

Back

Exponential phase.

Front

What occurs during the lag phase of bacterial growth?

Back

Bacteria adapt to their new environment before division.

Front

What characterizes the exponential phase of bacterial growth?

Back

Rapid cell division and population increase.

Front

What happens during the stationary phase of bacterial growth?

Back

Nutrient depletion and waste accumulation lead to a balance between cell division and death.

Front

What is the death phase in bacterial growth?

Back

A phase where the number of viable cells decreases due to nutrient depletion and toxic accumulation.

Front

How does nutrient availability affect bacterial growth phases?

Back

Nutrient availability influences the transition between growth phases, particularly from exponential to stationary.
