During ripening, what happens to malic acid?

Explanation:
During ripening, the fruit’s metabolism shifts toward using stored acids for energy and building blocks. Malic acid is gradually broken down as it feeds respiration, being converted to compounds such as pyruvate and CO2 (and related intermediates) that re-enter metabolic pathways. This consumption reduces the malic acid pool, so the fruit’s acidity falls while sugars accumulate. Dilution from water uptake can also lower concentration. In short, malic acid is degraded as ripening proceeds.
