bivalves have evolved diverse and highly specialised strategies for surviving in hypoxic episodes including pathways that are efficient both in terms of ATP production, and in minimising H+ and toxic end product accumulation. Under these circumstances, glycogen is metabolized to pyruvate and the cytosolic NADH/NAD+ redox ratio is balanced by the reduction of pyruvate to lactate. Alternatively, NAD+ can be recycled more efficiently by coupling an amino acid to pyruvate, with formation of opines such as alanopine, tauropine, octopine, and strombine. Specimens utilizing the octopine rather than the alanopine pathway will increase energy flow rapidly, developing a major ability to counteract environmental variations. The high ratio between malate dehydrogenase/lactate dehydrogenase is due to the ability of Pinna nobilis to turn on anaerobic metabolism as a consequence of environmental or anthropogenic stresses. Anaerobic pathways are not all equivalent in terms of energy production based upon maximum rates for ATP output (lactate > octopine > alanopine = strombine). The ODH pathway is probably able to realize a higher rate of energy production than either the SDH or ADH pathways
