Norepinephrine uses the Second Messenger System, which means, cells signal to each other what molecules have been released that will trigger a physiological reaction.

This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor (protein molecule), creating a variation that causes a chain-reaction, that will finally activate the Second Messenger. The latter will activate intercellular molecules that will be able to control the cell’s activity.

Which phase of the bacterial growth curve is defined by zero net growth due to a lack of nutrients and excessive waste products

uysha [10]

Bacterial growth curve-

The phase in the bacterial growth curve which is defined by zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.

Phases of the bacterial growth curve-

The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.

Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
Log phase- The second phase where the cells are dividing and increasing in numbers.
Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.
