Penicillin is produced by P. chrysogenum in a fed-batch culture with the intermittent addition of glucose solution to the culture medium. The initial culture volume at quasi-steady state is V₀ = 500 l, and glucose-containing nutrient solution is added with a flow rate of F = 50 l/h. Glucose concentration in the feed solution and initial cell concentration are S₀ = 300 g/l and X₀ = 20 g/l, respectively. The kinetic and yield coefficients of the organism are mm = 0.2 h^-1 , K_S = 0.5 g/l, and Y_X/S = 0.3 g dw/g glucose. Determine the concentration of glucose at t = 10 h at quasi-steady state

Out of these which of the following is true regarding the propensity of α-helix.

a. any amino acid which can take up desirable ϕ and ψ angle close to -57 and -47 will favour the formation of a α-helix

b. amino acid such a proline and glycine have lowest propensity will favour formation of α-helix.

c. if the resultant change in the value ΔΔG0 is positive then it will favour the formation of α-helix.

d. if the resultant change in the value ΔΔG0 is zero or close to zero then it will favour the formation of α-helix.
