What happend to that mass when the forest burns?

When the forest burns we will lose a huge amount of oxygen and animals will lose their home.

Explanation:

ΔG = -21.9kJ/mol

Explanation:

It is possible to make an algebraic sum of the ΔG's of the semireactions to obtain ΔG of a reaction.

If semireactions are:

(1) 1,3-Bisphosphoglycerate + ADP → 3-Phosphoglycerate + ATP ΔG = 0.1 kJ/mol

(2) 3-Phosphoglycerate → 2-Phosphoglycerate ΔG = 0.8 kJ/mol

(3) 2-Phosphoglycerate → Phosphoenolpyruvate + H₂O ΔG = 1.1 kJ/mol

(4) Phosphoenolpyruvate + ADP + H⁺ → Pyruvate + ATP ΔG = -23 kJ/mol

The sum of (3) + (4) gives:

2-Phosphoglycerate + ADP + H⁺ → Pyruvate + ATP + H₂O

And the net change in free energy is:

ΔG = 1.1 kJ/mol + (-23kJ/mol) = -21.9kJ/mol

I hope it helps!
