Ubiquinone e. Cytochrome c 7 The AG for hydrolysis of PEP to form p Resonance stablization of the product b Solvation of the produe toniration of the products d Tautomeriuation of the product e Better charge separation in products than 61 k/mol. The AG for hydrolysis of form ADP is -31 k/mol. What is AG" phosphorylation of ADP by PEP a. 31 k/mol b 1 /mol the reactants 46 k/mel d 92 k/imol e 92 k/mol 4 Aboul the following two reactions, which atement is trueExplanation / Answer
Answer:
C
The hydrogen bond is directional in nature -because the hydrogen atoms are covalently bonded to one atom and it is electrostatically attracted to another one
Answer 2
E
NADH has two peaks in its absorption spectrum but NAD+ has only one.
Answer 3
D
Since the solution form a tautomer which is highly stable so it is the reason for the favorable hydrolysis
