Question 1

Exergonic/Endergonic involves delta

Answer 1

G

Question 2

Why does hydrolysis of ATP yield E? (5 reasons)

Answer 2

1) Phosphoanhydride bonds are relatively weak (weak bonds break, strong bonds form -> E released)
2) ATP has a higher negative charge density than ADP - lots of repulsion so more stable if you take off a phosphate
3) Orthophosphate is very stable -> multiple resonance states
4) Enthalpy decrease
5) Entropy increases

Question 3

At equlibrium, delta G equals

Answer 3

0

Question 4

For Delta G to be negative even when Delta prime G is positive, RT ln (K) must be?

Answer 4

less than 1
