A spheroidal bacterium with a diameter of 1 mm contains 2 molecules of a particular protein. What is the molar concentration?

creativ13 [48]

Answer : The molar concentration is, $6.35\times 10^{-18}mol/L$

Explanation :

First we have to calculate the moles of protein.

$\text{Moles of protein}=\frac{\text{Number of molecules of protein}}{\text{Avogadro's number}}$

Number of molecules of protein = 2 molecules

Avogadro's number = $6.022\times 10^{23}molecules/mol$

$\text{Moles of protein}=\frac{2\text{ molecules}}{6.022\times 10^{23}molecules/mol}=3.32\times 10^{-24}mol$

Now we have to calculate the radius.

Radius = $\frac{Diameter}{2}=\frac{1mm}{2}=0.5mm=5.0\times 10^{-4}m$

Conversion used : (1 mm = 0.001 m)

Now we have to calculate the volume.

$V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\times 3.14\times (5.0\times 10^{-4}m)^3$

$V=5.23\times 10^{-10}m^3=5.23\times 10^{-7}L$

Conversion used : (1 m³ = 1000 L)

Now we have to calculate the molar concentration.

$Concentration=\frac{\text{Moles of protein}}{\text{Volume}}$

$Concentration=\frac{3.32\times 10^{-24}mol}{5.23\times 10^{-7}L}$

$Concentration=6.35\times 10^{-18}mol/L$

Thus, the molar concentration is, $6.35\times 10^{-18}mol/L$

Explain the importance of essential oil metabolism in animals.

Volgvan

Plant essential oils (EOs) and their compounds have proven in vitro efficacy as antimicrobial, antioxidant, immunodulating and anti-inflammatory agents. These substances deserve an important place as feed additives that are generally considered as safe. The available in vivo data show that EOs could find use as natural growth promoters in animal diets. However, the available evidence on the possible positive effects of these substances on nutrient digestibility and the function of the gut is rather limited. Also, the benefits of EOs’ applications in animal’s diets depend on diverse parameters. These parameters can be, on the one hand, the unstable composition and the different levels of addition in the diet, and on the other hand, variable animal genetic factors. A better understanding of the gastrointestinal tract microflora composition and activity is needed in order to maximize the use of EOs and to manufacture effective products. Essential oils could find application in cases where approved drugs or chemical substances are unwanted, for example, biological farming. Hope this helps! Mark brainly please!
