The following reaction occur during cellular respiration:
Pyruvate → Acetyl CoA + CO₂ (ΔG =-29 kJ/mol)
Is this reaction exergonic or endergonic? Does it produce a phosphate group that later yields energy by giving up a phosphate group? 

• A. The reaction is endergonic and involves the production of a high-energy molecule.
• B. The reaction is exergonic and doesn't involve the production of any high-energy molecules.
• C. The reaction involves the production of high-energy molecules but isn't either exergonic nor endergonic.
• D. The reaction neither involves the production of any high-energy molecules nor falls under either category.

Answer: (B)
