Gluconeogenesis from lactate is particularly important during periods of intense physical activity. As discussed before, when oxygen supply is insufficient, typically during intense muscular activity, pyruvate generated during glycolysis is converted into lactic acid by lactate dehydrogenase. Instead of accumulating inside the ... WebGluconeogenesis reactions and regulation. Gluconeogenesis is activated when energy is required (i.e., low ATP/AMP ratio) and inhibited if there is an excess of energy available (i.e., large ATP/AMP ratio). Gluconeogenesis is also stimulated by glucagon and inhibited by insulin (see “ Phosphofructokinase-2 ” for the mechanism). ebay chicken wire fence
