Answer:
Explanation:
Hello.
In this case, since the bond energy per C-H bond is 411 kJ/mol and we of course avoid the C-C bond since we are asked to compute the energy to break 7 C-H bonds, the 411 kJ/mol are multiplied by 7 as shown below:
Thus, we obtain the required bond dissociation energy. Note that propane CH₃-CH₂-CH₃ has seven C-H bonds; 3 from the first CH₃, two from the CH₂ and 3 from the last CH₃.
Best regards.
Answer:
B) stabilization by hydration
C) resonance stabilization
E) increase in entropy
Explanation:
The high phosphoryl potential of ATP results from structural differences that exist between ATP and it's product of hydrolysis. There is higher phosphoryl transfer potential from ATP than glycerol 3-phosphate.
There are some factors associated to the high phosphoryl-transfer potential of ATP which are;
1.)Electrostatic repulsion
2.) Resonance stabilization
3.) Increase in entropy.
4. Stabilization by hydration.
ATP has a phosphoryl-transfer potential which lyes between high phosphoryl-potential compounds that is a derivation of fuel molecules and acceptor molecules that needs the adequate addition of a phosphoryl group for cellular needs.
