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.

Enzyme X and Enzyme Y are both involved in monosaccharide metabolism. Enzyme X uses glucose as a substrate while Enzyme Y uses fructose as a substrate. At pH=7.0, Enzyme X has a Vmax of 10 μM/s while Enzyme Y has a Vmax of 20 μM/s. Both enzymes have a Km of 3.0 mM for their respective substrates. Which aspects of its reaction will be changed by Enzyme Y?
