A bacterial cell that contains an outer membrane and periplasmic space stains pink to red on Gram stain. Which one of the follow
anastassius [24]

Answer:

a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.

Explanation:

Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.

It should be noted that, epinephrine and norepinephrine are also known as adrenaline and noradrenaline, this is because they are secreted by the adrenal gland, and this gives rise to the term adrenergic.

Examples of adrenergic drugs are phenylephrine, clonidine and oxymetazolin among others.
