Calculate the diffusive force (J) experienced by potassium in a cell where the concentration gradient is 35 mM, the membrane wid
kodGreya [7K]

Answer:

Diffusive force J = 9590

Explanation:

From the given information:

Concentration gradient C₁ - C₂ = 35 mM = 35 × 10⁻³ M

membrane width Δ x = 1 cm = 10⁻² m

Solubility S = 1

diffusive area A = 10

Temperature T = 1° C = (273 + 1 )K = 274 K

Using the expression:

\text {diffusive force J}  = \dfrac{C_1-C_2}{\Delta x }\times T \times S \times A

J  = \dfrac{35 \times 10^{-3}}{10^{-2} }\times 274 \times 1 \times 10

J  = 3.5 \times 274 \times 1 \times 10

Diffusive force J = 9590

The antibiotic penicillin is isolated from
kykrilka [37]

The antibiotic penicillin is isolated from <u><em>Penicillium notatum</em></u> fungi

Penicillin was first discovered in 1928 and was used at St. Mary's Hospital, London, by Alexander Fleming to heal wounds due to its antibacterial properties.

Explanation:

Fungi and bacteria usually produce antibiotics (as secondary metabolites) for defense mechanism. They do so to limit competition for resources with other neighboring fungi or bacteria in their environment.  This is why when a fungus or bacteria establishes itself in an environment, you hardly see other fungi or bacteria types growing in their vicinity.
