Question

1. The difference between the two thermodynamic terms ∆G and ∆G° is:

a. ∆G is obtained at pH = 7.0 and ∆G° = is obtained at pH = 0
b. ∆G is expressed in kcal/mol and ∆G° is expressed in KJ/mol
c. ∆G is used for biochemistry and ∆G° is used in general chemistry
d. ∆G expressed how rapidlyh a reaction will occur but ∆G° only tells if it may occur
e. ∆G describes a reaction at any time between the start of reaction and reaching equilibrium but ∆G° only describes the reaction at equlibrium .

2. One difference between NAD+ and FAD is:

a. NAD+ is an oxidizing agent and FAD is a reducing agent
b. NAD+ is consumed as part of the diet but FAD must be synthesized by the body.
c. NAD+ can carry only two electrons but FAD can carry either one electron or two electrons
d. NAD+ remains permanently bound to an enzyme but FAD may diffuse between enzymes.
E. FAD and NAD+ are functionally equivalent

Answer 1

1.

a. Not, ∆G° is obtained at ph= 7.0

b. Not. ∆G° is expresed in kcal/mol

c. Not. Both are used in biochemistry, bioenergy, chemistry, phisics.

d. ∆G calculate the variation of energy not the velocity

e. Is the correct

2.

a. Is the correct

b. Not. Both are synthetized by our organism

c. Is the correct

d. Not both are bound to their enzymes

e. Not Their have totally different functions
