Lag phase quizlet. Lag phase represents a period of active growth during which bacteria prepare for reproduction synthesizing DNA various inducible enzymes. The exponential or log phase is a time of exponential growth. The first one lag phase happens at the start of every population which is slow in growth due to the small number of individuals.

Sodium ions diffuse into th muscle fiber causing a local depolarization that exceeds threshold and produces an action potential. Wound is closed after granulation tissue forms. The initial phase is the lag phase where bacteria are metabolically active but not dividing.

The length of the lag phase can vary considerably based on how different the conditions are from the conditions that the bacteria came from as. Log or Exponential Growth Phase 3. During this period called the lag phase the cells are metabolically active and increase only in cell size.

Death or Decline Phase. Secondary wound closure B. Lag exponential log stationary and death.

A healthy population will often have two lag phases. The binding of acetylcholine to its receptor site causes the ligand-gated Na channels to open and the postsynaptic membrane become more permeable to Na. Lag2 phase often occurs after exponential growth slowing growth usually due to carrying capacity and limiting factors.

The lag phase is an adaptation period where the bacteria are adjusting to their new conditions. Describe how a chemostat keeps cells in a state of continuous growth. Learn vocabulary terms and more with flashcards games and other study tools.

Cells reach their maximum rate of cell division during the lag phase. Microbial growth curve increases geometrically and the phase continues as long as cells have adequate nutrients and a favorable environment. What is a twitch describe its phases.

This next phase is called the contraction phase. At what phase in the bacterial growth curve in a patient do antibodies from the immune system and phagocytosis by white blood cells affect the progress of the disease. The time between the activation of a motor neuron until the muscle contraction occurs is called the lag phase sometimes called the latent phase.

There are four distinct phases of the growth curve. The lag phase occurs when an Action potential arrives at the p Calcium enters the presynaptic terminal and begin the release Ach is released into the cleft by exocytosis. In the lag phase cells are gearing up to begin dividing whereas in the exponential phase cells are dividing at a continuous rate.
