This chapter explores the impact of ocean acidification (OA), driven primarily by the absorption of anthropogenic CO2, leading to a decline in ocean pH and disrupting the carbonate system equilibrium, on energy metabolism and intermediary metabolism of marine shelled mollusks. OA poses significant threats to calcifying organisms such as corals and bivalves, with far-reaching consequences for marine ecosystems and vital services such as aquaculture and shoreline protection. The focus here is on OA’s impact on marine shelled mollusks, particularly bivalves and gastropods, emphasizing energy and intermediary metabolism. By examining species-, population-, and life stage-specific physiological responses to OA-induced metabolic disruption, including disturbances in energy acquisition, catabolism, calcification, and acid–base regulation, alongside potential compensatory mechanisms, this chapter provides insights into the adaptive capacity of mollusks and helps in predicting their long-term resilience or vulnerability to ongoing ocean acidification.
