The reaction converting glycerol to glycerol-3-phosphate is energetically unfavorable by 9.2 kJ. The reaction of ATP with water
maw [93]

Answer:

ΔG for overall reaction :  -21.3 kJ

Explanation:

Reaction of the conversion of glycerol to glycerol-3-phosphate is unfavorable and thus is coupled with second reaction that involves the conversion of ATP to ADP which is highly energetically favorable.

Reaction 1:  Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water

Reaction 2:             ATP  + H₂O ⇒ ADP + HPO₄²⁻ + H⁺

ΔG for reaction 1 : 9.2 kJ (non-spontaneous : Positive value)

ΔG for reaction 2 : -30.5 kJ (spontaneous : Negative value)

The overall coupled reaction is:

<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>

<u>ΔG for overall reaction : 9.2 kJ + (-30.5 kJ) = -21.3 kJ</u>

negative sign signifies that the overall reaction is spontaneous.

Identify one disadvantage to each of the following models of electron configuration:
LuckyWell [14K]

Answer:

Include:

--Dot structures do not show the distribution of electrons in orbitals and take up a lot of space.

--Arrow and line diagrams take up a lot of space and make it difficult to count electrons.

--Written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
